With just a few ingredients and the magic of Clearjel, you’ll have thick, glossy filling ready to spoon into pies, crisps, and cobblers whenever the craving strikes.
Why I Love This Recipe
There’s something satisfying about preserving seasonal fruit—and rhubarb is one of those fleeting gems you want to make the most of. This filling captures the unique tang of rhubarb, balances it with just the right amount of sugar, and thickens beautifully without becoming gummy (thanks, Clearjel!).
Whether you’re an experienced canner or just freezing batches for later bakes, this method is simple, safe, and incredibly rewarding.
🧾 Ingredients You’ll Need
- 5 pounds rhubarb, sliced
- 2½ cups sugar
- 2 tablespoons lemon juice
- ½ cup Clearjel (NOT cornstarch; this is canning-safe!)
🔄 Notes & Substitutions
- Clearjel: Be sure to use regular Clearjel (not Instant). It’s heat-stable and approved for safe canning.
- Lemon Juice: Adds acidity for safe preservation and brightens the flavor.
- No Clearjel? You can still make and freeze the filling, but don’t attempt to can it without a proper thickener.
👩🍳 How to Make Rhubarb Pie Filling
Step 1: Macerate the Rhubarb
Toss sliced rhubarb with sugar in a large bowl. Stir to coat and let sit for 2 hours at room temp to draw out juice.
Step 2: Prep for Canning
While waiting, prepare boiling water, jars, lids, and rings if you’re canning. Sterilize everything according to safe canning practices.
Step 3: Strain & Measure Juice
After macerating, strain the rhubarb and set aside the slices. Measure 3 cups of juice (add water if needed).
Step 4: Thicken the Base
In a large pot, whisk the juice with lemon juice and Clearjel. Bring to a boil over medium-high, stirring constantly until thick—about 1 minute.
Step 5: Add Rhubarb
Gently stir in the rhubarb slices. Bring back to a boil, continuing to stir to avoid scorching.
Step 6: Choose Your Storage Method
- Freezing: Ladle filling into freezer-safe containers, leaving 1” headspace. Cool, seal, and freeze.
- Canning: Ladle into hot jars, leaving 1” headspace. Remove bubbles, wipe rims, seal with lids and rings.
Step 7: Process
- Pints: Process in boiling water bath for 15 minutes
- Quarts: Process for 20 minutes
Adjust for elevation if needed.
Step 8: Cool and Store
Let jars cool undisturbed. Check seals, remove rings, and store in a cool, dark place. Refrigerate or freeze any unsealed jars.
🌟 Tips for Success
- Don’t skip the macerating step—it draws out liquid so the filling thickens correctly.
- Use Clearjel, not cornstarch—only Clearjel is approved for safe home canning.
- Avoid overcooking the rhubarb in the final step; it should be tender, not mushy.
