Not as a thickened, shelf-stable filling using the USDA/NCHFP recipe. Cook-type Clear Jel is the tested thickener; ordinary cornstarch, flour, tapioca, instant Clear Jel, and Sure-Jell pectin are not safe one-for-one substitutes because they can change density and heat penetration. If cook-type Clear Jel is unavailable, freeze the filling, or use a separate tested recipe for plain canned apple slices and add your preferred thickener after opening. Never improvise the thickener in a canning recipe.

How to safely can tested apple pie filling with cook-type Clear Jel
Prepare firm apple slices, use the exact tested ingredients, fill jars with one-inch headspace, and process them for the time required at your elevation.
What you need
- Firm, crisp apples
- Cook-type Clear Jel in the exact tested amount
- Granulated sugar, cinnamon, cold water, apple juice, and bottled lemon juice
- Clean pint or quart canning jars with new lids
- Boiling-water canner with rack and lid
- Large kettle
- Jar lifter, canning funnel, and headspace tool
- Accurate measuring cups and spoons
- Choose the complete tested recipe
Use the National Center for Home Food Preservation apple pie filling recipe from beginning to end. Confirm your elevation before heating the canner, and use cook-type—not instant—Clear Jel.
- Prepare the apple slices
Wash, peel, and core firm apples. Cut them into ½-inch-wide slices and hold them in an ascorbic-acid solution to limit browning.
- Blanch in measured batches
Place 6 cups of fresh slices at a time in 1 gallon of boiling water. Boil each batch for 1 minute after the water returns to a boil, drain, and keep the fruit hot and covered.
- Cook the tested thickened liquid
Combine the recipe's exact sugar, cook-type Clear Jel, cinnamon, water, and apple juice. Cook until thickened and bubbling, add the measured bottled lemon juice, and boil for 1 minute while stirring constantly.
- Fill without delay
Fold in the hot drained apples, fill hot jars immediately, remove air bubbles, and leave exactly 1 inch of headspace. Wipe rims and apply lids according to the manufacturer’s directions.
- Process for elevation
Process hot-packed pints or quarts in a boiling-water canner for 25 minutes at 0–1,000 feet, 30 minutes at 1,001–3,000 feet, 35 minutes at 3,001–6,000 feet, or 40 minutes above 6,000 feet.
Why regular cornstarch is not a canning substitute
A home-canning process is tested for a specific recipe density. Iowa State University Extension explains that regular cornstarch, flour, and tapioca can become dense, clump, break down during repeated heating, and interfere with heat moving throughout the jar. That is why a familiar stovetop thickener cannot simply replace Clear Jel in the canned filling.
Cook-type Clear Jel is a modified cornstarch that stays workable during preparation and processing, then develops the expected consistency as the jar cools. Use only the amount specified by the tested recipe; adding extra thickener also changes density.
Cook-type and instant Clear Jel are different
The tested canned pie filling uses regular cook-type Clear Jel. Illinois Extension specifically warns not to use instant Clear Jel in canned pie filling. Instant Clear Jel thickens without cooking and is intended for different applications, including some freezer fillings.
Sure-Jell is also not Clear Jel. Sure-Jell is a pectin product for jams and jellies, not the modified starch specified for pie filling. Similar names do not make the products interchangeable.
The tested one-quart formula
For one quart, the NCHFP table calls for 3½ cups blanched sliced apples, ¾ cup plus 2 tablespoons granulated sugar, ¼ cup cook-type Clear Jel, ½ teaspoon cinnamon, ½ cup cold water, ¾ cup apple juice, and 2 tablespoons bottled lemon juice. Nutmeg and one drop of yellow food coloring are optional; the coloring is not needed for safety.
If the apples lack tartness, the NCHFP directs adding another ¼ cup bottled lemon juice per 6 quarts of slices. Do not remove the bottled lemon juice, replace it with fresh-squeezed juice, or alter the proportions because the complete formula and process work together.
Processing time changes with elevation
The NCHFP process is for hot-packed pint or quart jars in a boiling-water canner. Process for 25 minutes at 0–1,000 feet, 30 minutes at 1,001–3,000 feet, 35 minutes at 3,001–6,000 feet, and 40 minutes above 6,000 feet. Start timing only when the water returns to a full boil.
Leave 1 inch of headspace and process immediately after filling. A jar sealing after an improvised recipe does not prove that the center received a safe heat process.
Safe options when you cannot find Clear Jel
Illinois Extension recommends freezing pie filling when cook-type Clear Jel is unavailable. Another option is to use a separate tested recipe for plain canned apples, then drain or heat the fruit and add cornstarch, flour, tapioca, or another preferred thickener after opening. Do not merely swap that alternative into the NCHFP pie-filling formula.
Freezing is especially practical when you want to use an instant thickener or customize sweetness. Label the package, keep it at 0°F or below, and follow a tested freezer recipe rather than treating a freezer method as shelf-stable canning.
Is home-canned apple pie filling an Amish practice?
No. Water-bath canning apple pie filling is a general modern food-preservation method, not an exclusively Amish practice. The Young Center cautions against describing Amish communities as uniform because practices and technology choices vary across affiliations and church districts.
An Amish-inspired pantry may emphasize seasonal fruit and avoiding waste, but every measurement and processing time in this guide comes from current USDA-based and university Extension guidance—not from an invented cultural claim.
Frequently asked questions
Can cornstarch replace Clear Jel in canned apple pie filling?
No. Cornstarch changes the filling's density and can interfere with heat penetration. Use cook-type Clear Jel in the exact tested recipe, or choose freezing or a separate plain-apple canning recipe.
Can flour or tapioca replace Clear Jel?
No. Flour and tapioca are not interchangeable with cook-type Clear Jel in the tested canned pie filling. Add a preferred thickener only after opening a separately canned plain-apple product, or use it in a freezer recipe.
Can instant Clear Jel be used for canning?
Not in the NCHFP apple pie filling recipe. Illinois Extension specifies regular cook-type Clear Jel for canning and says instant Clear Jel is not the same product for this use.
Is Sure-Jell the same as Clear Jel?
No. Sure-Jell is pectin used for jams and jellies. It is not the cook-type modified starch tested for canned fruit pie fillings.
How long do you water-bath apple pie filling?
For the NCHFP hot-pack recipe in pints or quarts: 25 minutes at 0–1,000 feet, 30 minutes at 1,001–3,000 feet, 35 minutes at 3,001–6,000 feet, or 40 minutes above 6,000 feet.
What can I do if I cannot buy cook-type Clear Jel?
Freeze the pie filling, or can plain apple slices with a separate tested recipe and thicken after opening. Do not substitute ordinary starch in the tested shelf-stable pie filling recipe.
