How to Dehydrate Fruit (Cherries, Blueberries, Grapes, Raspberries & Blackberries)

August 2, 2022 by Melissa Norris 26 Comments

Learn to make the best dehydrated fruit and enjoy your summer harvest all year long. Dehydrating fruit works especially well for cherries, grapes, and berries. Using an oven or a dehydrator, use my secret trick to speed up the dry time.

Why I Love Dehydrated Fruit

Dehydration is an excellent way to preserve your fruit, especially berries for year round use. It's shelf stable and can be eaten as is.

It's light, meaning easy to pack and shove into pockets. And you can use it to make delicious candies, treats, cakes, and breads.

Dehydration, when done at a low temperature, makes it “raw” food, retaining almost all of the nutrients.

This year as I was dehydrating trays of cherries my husband asked why I was doing it if we never eat them? Unbeknownst to him, I dehydrate them every year and just tuck them away! We don't get many cherries for dehydrating, so they're my special treat!

We're blessed on our homestead to have raspberries, blueberries, and a plethora of blackberries. I turn most of our bounty into various jams. I like to keep the sugar low in most of my jam recipes, and I like to make jam without pectin.

If you're in need of some jam recipes, here are some of my favorites:

For more info on canning jam, be sure to check out this post on making jams and jellies like a pro.

Even though my love of canned jam runs deep, one thing they're not great for is for traveling or packing in lunch boxes.

Frozen and then thawed berries aren't friendly for munching on, although I will say freeze-dried fruit is quickly becoming another favorite go-to in our house, freeze dryers are cost prohibitive for some.

So in comes dehydration. I confess that I overlooked dehydrated fruit for years. Mostly because I tried dehydrating blueberries about 10 years ago and after three days straight, I still had half shriveled but not dehydrated berries.

I'm so glad I gave it another try after learning the trick to speeding up the dehydrating time.

Supplies Needed

If you plan on doing much dehydrating, I recommend getting an actual dehydrator. They are a great investment and make dehydrating a “set it and forget it” kind of task.

Can you use your oven with the door propped open? Yes, but you can't control the temperature, and then you can't cook in your oven. Plus, if you have little ones, leaving your oven door open isn't probably the safest thing.

Nesco Dehydrator

I have a Nesco square dehydrator and am very happy with it. I purchased it many years ago and it still runs like a champ.

It's quiet and gets the job done. I haven't had any problems with it and have run it close to a week straight when doing cherries and then a batch of blueberries.

A Nesco dehydrator will be a more economical approach if you're just getting started. And I highly recommend getting these screens for sticky fruit and fruit leather (they're even dishwasher safe!).

Excalibur Dehydrator

If you plan on doing a lot of dehydrating, you'll want to consider the Excalibur dehydrators. This is a great upgrade for those dehydrating large batches of fruit at a time.

I don't have one, but know many people who do, and they all say it's the workhorse of dehydrators and well worth the investment.

It is more expensive than the Nesco. However, the air blows from the back of the unit instead of the top, making it more efficient.

This is the cheapest deal I've found for an Excalibur dehydrator.

Pro Tip: If you're dehydrating multiple batches back to back, consider setting your dehydrator up outside in a safe location to keep from heating up your house during the hot summer months!

How to “Check” Your Berries Before Dehydrating

When you're dehydrating berries, you need to use one simple trick to cut hours and days off your dehydrating time. You need to check your berries.

“Checking” is merely piercing the skin so the moisture can evaporate more quickly. Berries are mostly water, after all. Checking should be used with blueberries, cranberries, and grapes, or any other similar type of fruit.

I pit my cherries before dehydrating, so I'm technically checking them when I pit them. There are multiple ways you can “check” your berries to speed up the dehydrating process.

Poke each berry with a pin – Take a safety pin or sewing pin and poke a hole in each berry. If you're doing a small amount, this might not take very much time, but if you're doing tray fulls, this is going to take forever.
Boil/steam your berries – Briefly boil or steam berries until they've split their skins, but not enough to cook them. This method works well, but you will lose some nutrients by heating them.
Freeze your berries – This is the method I prefer. Simply toss your berries into the freezer for a few hours. It will rupture the cells and make your berries good to go. When it's the middle of summer, and a task takes no work on my part (okay, besides the harvesting), I'm all about that!

Sometimes getting kids involved in the process is fun, if they can safely poke the berries then this is a great option, however, I'm sure many of you would agree that option #3 is the best!

How to Dehydrate Berries

After you've prepared your berries by checking them, spread them out on your dehydrating trays. (For sticky berries or fruit, I highly recommend the dehydrator mats for easy clean-up.) You want the berries or fruit to be evenly spaced so they dehydrate at the same rate.
With our blueberries, we have several different varieties, which means different sizes of berries. I recommend putting the smaller berries on one tray and the larger ones on another. I didn't the first time and had to manually separate them as the smaller ones were done before the bigger ones. So save yourself some time here.
Turn on your dehydrator and let it do its thing. The fruit setting on mine is 135 degrees.
Even with “checking”, berries take quite a while to dehydrate fully. My cherries took 28 hours. My small blueberries were done at about 24 hours, whereas the larger ones took 36 hours.
Rotate your berries or fruit after 12-hour mark for even drying. My top tray dehydrates a tad faster than the bottom one, especially when I've got all four stacked.

How to Know When Fruit is Dehydrated?

If you're unsure if your fruit is fully dehydrated, you can sample a few. If you feel liquid, then put them back in. Some of my smaller berries got hard, so I knew they were fully done. You want chewy berries but not overly sticky or wet. Otherwise, they start to mold.

Another way to check them is to place a handful of still-warm fruit (it's important they're still warm) into a jar or plastic bag and seal tight. If you notice any condensation forming on the jar or bag the fruit isn't fully dehydrated.

How to Store Dehydrated Fruit

Store dehydrated fruit in an air-tight container in a dark, cool place for optimal shelf life.

Unlike freeze-dried fruit, dehydrated fruit is best when eaten within a year. This is why I like to plan how many fruit and berry bushes we need for our family for a year's worth of fruit.

How to Use Dehydrated Fruit

Use your dehydrated fruit in homemade breads, muffins, granola, candy, or just by the handful! Be warned, they're kind of addicting.

There you have it, my favorite way to dehydrate fruit and my time-saving tips when dehydrating blueberries, cherries, and grapes! Have you tried this method or other home food preservation methods before?

Cherry Pit Vinegar

Move over apple scrap vinegar, you’re not the only fruit that can be used twice for delicious things.

Ingredients

1 cup cherry pits*

2 cups vinegar (any vinegar of your choice)

Place the pits (leave all the bits of cherry fruit on them you can, this helps with the flavor) in a clean glass jar. Cover with vinegar and place out of direct sunlight. White vinegar takes on some color if using red cherries whereas apple cider vinegar won’t change as much in color, but both work equally as well.
Allow to steep for two to three weeks. Strain, place back in a glass bottle, and enjoy your cherry pit flavored vinegar!

*Only use uncracked pits. As long as you don't try to smash them with a hammer, they’re not cracked. Cherry pits (most stone fruit pits) do contain small amounts of cyanide. This is only exposed when they’re cracked, smashed, or ground up.

Notes

For sticky berries or fruit, I highly recommend the non-stick mats for easy clean-up. You want to the berries or fruit to be evenly spaced so they dehydrate at the same rate.
Even with “checking”, fruit takes quite a while to fully dehydrate. My cherries took 28 hours. My small blueberries were done at about 24 hours, whereas the larger berries took 36 hours. This is still better than three days though!
Dry Test – To know if berries are dry, do the “dry test”. Place a handful of still-warm berries into an airtight container (sealed Mason jar or sealed plastic baggie). Let them sit for 10-20 minutes and check the sides of the container. If you see any moisture or condensation on the jar or bag, the fruit isn't dry and needs to continue dehydrating.

Canned Tomato Sauce Recipe (+ Water-bath & Pressure Canning)

August 2, 2022 by Melissa Norris 130 Comments

Home-canned tomato sauce from vine-ripened tomatoes may as well be an entirely new product as there is no comparison to store-bought. It's incredibly easy to make and you can water bath or pressure can it for long-term food storage.

Follow this easy step-by-step tutorial for my favorite canned tomato sauce recipe and enjoy it spiced up as pizza or spaghetti sauce, use it in chili, for tomato soup, barbecue sauce, cabbage rolls, and so much more.

Why I Love This Recipe

Learning how to can tomato sauce is life-changing. No, seriously, with a single jar you can create pretty much anything your heart desires with tomato sauce as the base.

Using my principles for growing a year's worth of tomatoes (and then saving the seeds for the following year's garden), I am able to can our entire year's worth of tomato sauce. Never having to purchase tomato, pizza, or spaghetti sauce from the store is pretty amazing. In fact, I dare say this may be the most versatile item in my home food storage.

And let me tell ya, if you've never had homemade tomato sauce before made from vine-ripened tomatoes, then you've never had tomato sauce before. All else is an imitation, my friend.

If you're struggling to grow enough tomatoes to put up for sauce, you can always buy them from the farmer's market. But you may also be interested in how to prune tomatoes for a better harvest, or even my 10 tomato growing tips for a disease-free harvest.

How Do You Can Tomato Sauce?

The best part about canning homemade tomato sauce is that you've got options! (A girl can never have too many options for canning recipes, right?)

You can use both water bath and pressure canning methods for this canned tomato sauce recipe. Update: you can use a steam canner, as long as the processing time is 45 minutes or less (I incorrectly said 30 minutes but it is actually 45 minutes, yay). Keep reading below to see which option best suits your needs.

What Tomatoes Make the Best Sauce?

First off, you can use any tomato, but truly, paste tomatoes are the best for making sauces.

Why, you ask? (I love it when you ask questions, I truly do!)

Paste tomatoes have less water inside and are fleshier. This results in a thicker sauce without so much reduction time. And I'm all about saving time in the kitchen!

Some good paste tomato options are Roma tomatoes and, of course, the mother of all paste tomatoes (and quite possibly the best paste tomato of the bunch) is the heirloom San Marzano Lungo No. 2. I grow them every.single.year.

This also happens to be the variety that frequently ripens first, so it's a double win in my book. We liked the flavor diced and tossed onto pizza, but it really shines in sauces and pastes.

How Many Tomatoes Do I Need To Make Tomato Sauce?

You need a lot of tomatoes at once to make tomato sauce. This may be difficult if you don't have a large number of tomato plants and your tomatoes are ripening over a long span of time.

To allow for this without needing to make small batches of sauce, you can freeze your tomatoes whole in gallon ziplock bags until you have enough to move forward with this recipe.

The bonus of freezing tomatoes is that, as they defrost, you're actually able to peel the skins off, eliminating the step of having to roast them in the oven in batches (watch the video above to see how to do this if you're working with fresh tomatoes).

If you didn't grow enough tomatoes in your garden for sauce, you can buy a flat or two at the local farmer's market or barter with a friend. It's up to you how you source them, but for this canned tomato sauce recipe, you'll want at least 20 pounds of tomatoes to make about 7 pints of sauce.

Ingredients

Tomatoes (about 20 pounds makes 7 pints of sauce), I recommend San Marzano, Roma and Amish Paste, or another paste tomato, but remember, any tomato will do!
Bottled lemon juice (1 Tablespoon per pint jar and 2 Tablespoons per quart jar) it's important to use bottled juice from concentrate as fresh lemons vary in their acidity.
Salt (1/4 teaspoon per pint jar and 1/2 teaspoon per quart jar) I like to use Redmond Real Salt, but any sea salt will do as long as it doesn't contain iodine or anti-caking agents.
Dried Basil (1/2 teaspoon per pint jar and 1 teaspoon per quart jar) I don't like adding dried herbs to my jars anymore because I feel like they lose flavor during the canning process, instead, now I add my herbs after opening my jars of canned sauce for whatever recipe I'm using it for.

Making This Tomato Sauce Recipe

1. The first step, pick yourself some tomatoes! I didn't bother weighing out my haul, it was approximately 90 ripe tomatoes which I'm guessing came close to about 20 pounds of tomatoes. It yielded three one-quart jars plus a one-pint jar in the end.

2. Slice the tomatoes in half and remove the inner seeds and white membrane.

3. Lay the tomatoes, skin side up, on a cookie sheet and place in a preheated 350 degree F oven for 5 minutes, or until the skins begin to come loose from the flesh.

4. Remove skins and reserve in a bowl (I like to either dehydrate or freeze dry my seeds and skins to then pulse into a powder and use to thicken soups!). If you want to skip this step of removing the skins, I used to simply chop my tomatoes and add them to the stockpot, cook them down, mash them, and then put the sauce through a food mill to remove the skins. But I've since decided that roasting and removing the skins first saves time in the end.

5. Place the remaining tomatoes into a food processor or high-powered blender and give it a quick pulse to liquefy the contents. If you don't have a blender or food processor, you can mash the tomatoes (as shown in the photo above).

NOTE: Keep track of how much liquid you end up with, this amount will be necessary to know how many jars to prepare for canning.

6. Pour all tomato sauce into a large stockpot and bring up to a simmer and allow to reduce until the sauce is as thick as you like it. For my paste tomatoes, this usually means reducing it for about 40 minutes which allows about 1 inch of the liquid to evaporate. But my sauce is already pretty thick right from the start. This is purely preferential and will vary based on tomato varieties.

7. Meanwhile, prepare your jars, gather your lids, and either your water bath canner or your pressure canner.

8. To each jar, add a small amount of tomato sauce, then bottled lemon juice, salt, and optional herbs (see ingredients above for amounts).

NOTE: Lemon juice (or citric acid), salt, and herbs should be added to each individual jar, not the pot of tomato sauce. And you must add the bottled lemon juice for safe shelf stability.

9. Fill jars with tomato sauce up to a 1/2-inch headspace for water bath canning and 1-inch headspace for pressure canning. I typically like to pressure can because it takes less time.

10. Run a spatula around the jar circumference to remove air bubbles. Add more tomato sauce if needed to keep 1/2-inch or 1-inch headspace depending upon your method of canning.

11. With a damp clean cloth, wipe the rim of the jar clean. Place on lids and screw down the bands until resistance is met, then to fingertip tight.

Water Bath Canning Instructions

1. Place jars on a rack inside your water bath canner.

2. Make sure at least 1 inch of water is covering the tops of the jars.

3. Once you've got rolling boiling water, add lid and process pint jars for 35 minutes or quart jars for 40 minutes.

NOTE: See recipe notes for altitude adjustments above 1,000 feet in elevation.

4. Turn off heat and remove the lid from the canner. Allow jars to rest inside the water bath for 5 minutes.

NOTE: If you remove jars immediately, you run the risk of cracking the jars or the siphoning of liquid, which can inhibit a proper seal.

5. After the five minutes have passed, using a jar lifter, carefully lift jars out of the canner and place them in a draft-free area on a kitchen towel folded in thirds. Never place hot jars on a cold countertop.

6. Allow jars to rest, untouched for at least 12 hours, 24 hours if you have the counter space.

7. Remove bands and check seals then move to the pantry for storage. (If any jars didn't seal, store them in the refrigerator and use them within a day or two.)

Pressure Canning Instructions

1. Add water to the pressure canner, place the inner rack inside, and load jars.

2. Lock the lid, bring to a boil, and allow the pressure canner to vent steam for 10 minutes.

3. Put the weight on and allow the canner to come up to 10 pounds of pressure (or use a weighted gauge, depending on your pressure canner).

NOTE: See recipe notes for altitude adjustments above 1,000 feet in elevation.

4. Start processing time after weight begins rocking and hissing, or dial gauge reads 10 pounds of pressure.

5. Process both pint and quart-size jars for 15 minutes.

6. Allow pressure canner to cool down naturally and for pressure to return to normal.

7. Carefully remove the hot lid and wait another 10 minutes before taking jars out of canner.

NOTE: If you remove jars immediately, you run the risk of cracking the jars or the siphoning of liquid, which can inhibit a proper seal.

8. Using a jar lifter, carefully lift jars out of the canner and place them in a draft-free area on a kitchen towel folded in thirds. Never place hot jars on a cold countertop.

9. Allow jars to rest, untouched for at least 12 hours, 24 hours if you have the counter space.

10. Remove bands and check seals then move to the pantry for storage. (If any jars didn't seal, store them in the refrigerator and use within a day or two.)

NOTE: If you have enough tomato sauce to fill all the jars needed for a run in the pressure canner, I'd use the pressure canner. Food may reach a hotter temperature in the pressure canner, but because it's processed for less time, it retains more of the nutrients. But, if you don't have enough jars or don't have a pressure canner, the water bath is completely safe with this recipe.

Now stand back and look at those gorgeous scarlet jars, just begging to be simmered all day for spaghetti, in chili, or in these slow cooker cabbage rolls.

Seriously, does anyone else like to sit and stare at the rows of home-canned food, or am I the only one weird that way? I'm hoping now that you know how to can tomato sauce, you'll be staring at them, too.
