Canning Strawberry Rhubarb Filling

Aug 20, 2025 | Blog, Canning, Food, Preserving, Recipes

Today, I found myself in a bit of a rhubarb crisis — those stalks were giving me the side-eye from the fridge. So, I thought, why not whip up some Strawberry Rhubarb Filling? I’ve concocted this delightful pie filling more times than I can count, usually sending it straight to the freezer like it’s on a vacation. But today, I’m feeling adventurous and decided to can it instead! That way, I can avoid turning my freezer into a game of Tetris with one less item. Who knew canning could be so liberating? Let’s see how this goes — fingers crossed I don’t end up with a science experiment!

In this culinary escapade, I decided to give Clear Jel a whirl since it’s the shiny new star in the canning world, leaving cornstarch feeling a tad outdated. Once my filling was all dressed up and ready to party, I plopped it into jars like they were VIP guests and sent them off for a 30-minute soak in the water bath canner. Who knew canning could be so glamorous?

As soon as I crack open one of these jars and give it a taste, prepare yourselves for a flood of my genius culinary critiques! Who knows? It might be a masterpiece or a total disaster — either way, I’ll share my hilarious verdict!

For this round I used the recipe on Creative Homemaking.

Ingredients
  

  • 5 cups rhubarb, diced
  • 5 cups strawberries, sliced
  • 2 cups sugar
  • 1 cup Clear Jel
  • 2 cups Water
  • 8 Tbsp Lemon Juice

Instructions
 

  • If you find yourself short on strawberries or rhubarb, don’t panic! You can totally skimp on one of them — just remember to hit that magical number of 10 cups of fruit. So, if you’ve got a strawberry shortage, toss in some extra rhubarb, and vice versa. Just think of it as a fruity balancing act, and may the odds be ever in your favor!
  • Wash the rhubarb and then dice it into small pieces
  • Wash your strawberries and cut
  • Combine sugar and Clear Jel in a large stock pot. Add water. Stir. Cook on medium heat until mixture boils and thickens. Add water if it becomes too thick.
  • Stir in lemon juice. Boil for 1 minute, stirring constantly.
  • Add Strawberries & Rhubarb
  • Fill quart jars leaving 1 1/2" headspace
  • Wipe the rims of the jars with a paper towel. Place the rings and lids on the jars finger tight.
  • Process in water bath canner for 30 minutes
