Rhubarb Canning Recipes

As one of the first items that can be harvested, I can’t help but think of rhubarb as a symbol of spring.

The other day I overheard a woman tell an elderly man "Grandpa, this rhubarb sauce was made with the rhubarb from your garden, so you have to taste it and tell me if it tastes right." The conversation made me feel warm inside.

Spring is here!

I think most anybody with a rhubarb plant in their yard looks forward to the first rhubarb sauce for the year. You can also can the sauce so you can have some in the middle of winter.


Since Rhubarb is acidic, you can safely preserve rhubarb sauce using the water bath method. Fill hot half-pint jars with hot rhubarb sauce, leaving 1/4 inch headspace and process for 10 minutes in a hot water bath.

High altitude instructions
1,001 - 3,000 feet : increase processing time by 5 minutes
3,001 - 6,000 feet : increase processing time by 10 minutes
6,001 - 8,000 feet : increase processing time by 15 minutes
8,001 - 10,000 feet : increase processing time by 20 minutes

If there is anybody who has never made rhubarb sauce, I suggest that you give it a try. Even a very simple sauce with nothing but rhubarb and sugar makes a nice topping for ice cream or pound cake.

I only use about 2 tablespoons of sugar for each cup of chopped rhubarb, but you can use more or less according to your taste. Cook the rhubarb until soft stirring frequently. A little bit of water in the pan helps keep the rhubarb from sticking until the liquid starts cooking out of the rhubarb. When the rhubarb is soft, add the sugar and cook to boiling, stirring constantly. Of course, you can spice it up with cinnamon, nutmeg, ginger, or whatever spice sounds good to you.

You can also add, pineapple, strawberries, raspberries, or blueberries. All of these are high acid so the canning instructions remain the same. I will write more next time about how to tell if a modification to a recipe changes the canning method that needs to be used in order to ensure food safety.

Rhubarb Jam

This recipe is adapted from Culinary Arts Institute Encyclopedic Cookbook. This cookbook was written in 1950 (when the "Open Kettle" method of canning was still considered safe.) Any canning recipes that you get that use the open kettle method, should be updated in order to ensure food safety. I plan to have a post soon on unsafe processing methods.

The recipe depends on the pectin in the orange peel so use the peel and all. Yield is about 6 half-pint jars

2 oranges

3 cups sugar

Process oranges in a blender or food processor. Combine with remaining ingredients. Cook to 220°F (on a candy thermometer). Fill hot jars leaving 1/4 inch headspace. Add lids and process in a hot water bath for 10 minutes.

Two Strawberry Jam Recipes

Berry season will be upon us in a few weeks (in Iowa, anyway). I figure that the month of May is a good time to share recipes for various jams, sauces, and syrups that can be made with all those delicious berries. In June, I plan to move on to vegetables.

Even if you don't grow your own berries, frozen berries actually make just as good of jam as fresh ones. In fact, if you don't seem to have the time to make jam as you pick the berries, one idea is to freeze the berries, and make jam later.

Now, on with the recipes.


Strawberry -Rhubarb Jam
This recipe adapted from the Ball Blue Book. I admit that my copy of the Blue Book is getting kind of old, so if I am going to be blogging about it, maybe I should buy a new copy and see what changes have been made. This recipe yields about 6 half pint jars.

4 cups crushed strawberries
2 cups chopped rhubarb (about 4 stalks)
1/4 cup lemon juice
1 package powdered pectin (more about pectin in my next post)
51/2 cups sugar

Combine strawberries, rhubarb, lemon juice and pectin in a large sauce pot. Bring to boil over high heat. Add sugar, stirring until dissolved. Bring to a rolling boil. Boil for one minute, stirring constantly. Remove from heat. Skim foam, if necessary. Fill hot jars, leaving 1/4 inch headspace. Add lids and process for 10 minutes in a hot water bath.

Strawberry-Kiwi Jam

3 kiwi (peeled and chopped)
1 tablespoon lemon juice
1 package powdered pectin
5 1/2 cups sugar

The green color from the kiwi actually doesn't show up in the finished product. However, the flavor of the kiwi shows up in the taste. Read more...
