Learning to live more frugally and more self-sustainable includes using and eating season foods. It’s a bonus if you grow it all yourself, but it’s almost impossible to grow everything and there’s no reason to miss out on certain foods if you don’t grow it yourself.

Purchasing food as it comes in season is a great way to have fresh local food at a cheaper price. I try to purchase it from a local farmer if I don’t grow it myself or a farmer’s market, but even your grocery store will have lower prices on in season food.

May and June are a prime time for rhubarb, meaning  and the tail end of asparagus season. I’ve put almost 20 quarts of pickled asparagus and am planning on one more run this week. Here’s how to make and can pickled asparagus.

I had two bag fulls of rhubarb on the counter from a dear friend of ours. Rhubarb will store in the fridge for a week or two, but the ends will become rubbery and need trimmed. Important note: Only the stalks of rhubarb are safe to eat. The leaves our poisonous and should not be consumed or fed to animals.

It was fast becoming to the point I needed to do something with said rhubarb. My freezer is jam packed and we’ll be butchering our meat chickens in less than a few months, so I didn’t want to add anymore frozen produce to my stores.

Our strawberries are a few weeks away from becoming ripe and I have 8 cups of frozen rhubarb already designated to jam making. When I’m at a loss on what to make, I have one canning book I know I can turn to with a ton of recipes and ways to can.

Rhubarb is one of my favorite spring foods. It’s the perfect balance of tart paired with sweetness, like nature’s version of sweet tarts, and just as addicting. Rhubarb is known for it’s tongue tantalizing delights as a dessert from rhubarb dump cake (with a homemade from scratch cake mix), strawberry rhubarb jam, rhubarb pie, rhubarb and blueberry pie, I can’t think of a way rhubarb doesn’t work. I’ve even make it into a barbecue sauce that is divine. You might say I have a bit of a crush on rhubarb.

 

3 Ways to Preserve Rhubarb

  1. Freezing– to freeze rhubarb, rinse, dry and chop into uniform pieces, about a 1/2 inch. I vacuum pack mine into 4 cup portions as most of my recipes all for 4 cups of rhubarb. You can also use frozen rhubarb to later make into jam and desserts. I highly recommend a Food Saver vacuum sealer if you don’t have one. It allows me to keep my frozen foods months longer.
  2. Rhubarb strawberry jam. This is a favorite and I plan on making with Pomona’s Pectin this year so I can make a more low sugar version.
  3. How to can rhubarb, aka stewed rhubarb. Below are the tutorials for canning rhubarb recipes

The sugar will pull out the juices from the rhubarb stalks, creating a lovely rhubarb syrup.

2. Wash 4 pints in warm soapy water and rinse. Fill water bath canner with water and begin to heat. Fill a kettle with a few cups of water and bring to a boil.

3. Dump rhubarb and syrup into a large pot. Bring to a boil and boil for 30 seconds, stirring. Take off of heat and ladle 2 cups of rhubarb into each pint jar with a generous 1/2 inch head space. Pour syrup over rhubarb, dividing it evenly between the four jars to a 1/2 inch head space. Remove air bubbles by running a spatula or knife around the outside of the jar and add more syrup if needed. If you run short on syrup, add boiling water (hence the kettle boiling). Wipe rim of jar clean, put lids on, and screw down bands.

4. Place in rack and immerse in water bath canner. Bring canner to a boil, making sure at least 1 to 2 inches of water cover the top of the lids. Process pints for 10 minutes with lid on. After 10 minutes, remove lid, let sit for 5 minutes, and then transfer jars onto a towel folded in thirds. Let jars cool for at least 12 hours without moving and check seals.

Pressure Canning Rhubarb Instructions

Follow above recipe through step 3.

Place rack in pressure canner and ad specified amount of water. Place jars on rack. Allow pressure canner to vent for 10 minutes. Use 5 pounds of pressure and process both pint and quart sized jars for 5 minutes.

It’s normal for the rhubarb to float to the top of the jar. Don’t worry. Looking for some recipes using canned rhubarb? Use in place of fresh for rhubarb pies, desserts, cakes, muffins, or just plain old eating.

What are your favorite ways to preserve rhubarb? While freezing can be great in the short term, learning how to can rhubarb, including pressure canning rhubarb, have quickly become my preferred methods.
