Canning cherry pie filling is a water bath project that works when you use cook-type Clear Jel, bottled lemon juice, and a tested recipe. One quart fills an 8- or 9-inch pie, so a single afternoon of pitting turns July fruit into a winter dessert you can open and bake.
Do not thicken the jars with cornstarch, flour, tapioca, or instant Clear Jel. Those starches can clump, thin out after processing, or slow heat as it moves through the jar. Mix cook-type Clear Jel with the sugar first, keep the bottled lemon juice exactly as written, and process pints and quarts for the same time based on your altitude. That is the short version. The rest of this guide is how to do it without a runny jar or a sticky lid.
What You Need Before You Pit Anything
Buy cook-type Clear Jel before you buy extra cherries. It is a modified cornstarch made to stay thick after canning and baking. Instant Clear Jel is a different product and will not hold up in the canner. Grocery stores rarely stock the cook-type version, so order it or find it at a bulk foods shop first.
You also need:
- Firm, ripe sour cherries, fresh or unsweetened frozen
- Granulated sugar
- Bottled lemon juice, not fresh-squeezed
- A water bath canner, pint or quart jars, new lids, and rings
- Optional cinnamon and almond extract
A cherry pitter saves your thumbs. Wide-mouth quarts are easier to fill than regular-mouth jars because the filling is thick and sticky. Wash jars, keep them hot, and start heating the canner while you pit. You want the canner hot, not necessarily at a full boil, when the first jar is ready.
The Tested Recipe for Canning Cherry Pie Filling
The National Center for Home Food Preservation cherry pie filling formula is the one to follow for a water bath pack. It is written for sour cherries and scales cleanly from one test quart to a full 7-quart canner load.
| Ingredient | 1 quart | 7 quarts |
|---|---|---|
| Fresh or thawed sour cherries | 3 1/3 cups | 6 quarts |
| Granulated sugar | 1 cup | 7 cups |
| Cook-type Clear Jel | 1/4 cup + 1 Tbsp | 1 3/4 cups |
| Cold water | 1 1/3 cups | 9 1/3 cups |
| Bottled lemon juice | 1 Tbsp + 1 tsp | 1/2 cup |
| Cinnamon, optional | 1/8 tsp | 1 tsp |
| Almond extract, optional | 1/4 tsp | 2 tsp |
Food coloring is listed in the original recipe and is optional. Skip it unless you want a brighter red.
Rinse and pit fresh cherries, then hold them in cold water. An ascorbic acid soak (1 teaspoon ascorbic acid crystals, or six 500 mg vitamin C tablets, in 1 gallon of water) helps keep the stem ends from browning. Blanch 6 cups of cherries at a time in 1 gallon of boiling water. Start timing when the water returns to a boil, cook 1 minute, drain, and keep the fruit covered and hot.
Whisk the sugar and Clear Jel together in a large pot while the cherries stay warm. Add the cold water and optional spices. Cook over medium-high heat, stirring the whole time, until the mixture thickens and bubbles. Add the bottled lemon juice and boil 1 minute, still stirring. Fold in the hot drained cherries and ladle at once into hot jars, leaving 1 inch of headspace. Debubble, wipe the rims clean, apply lids fingertip-tight, and process immediately.
Fresh Cherries Versus Frozen Cherries
You can can either one. The method changes slightly, and that change matters more than most recipe cards admit.
If you are working with fresh sour cherries
Blanch them. The brief boil softens the fruit so it folds into the thick gel instead of sitting in dry clumps. Keep the blanched cherries hot. Cold fruit dropped into a hot gel cools the pot and can leave underheated spots in the jars.
If you thawed unsweetened frozen cherries
Use unsweetened fruit. If sugar was added, rinse it off while the cherries are still frozen. Thaw, collect the juice, and use that juice to replace part of the water in the recipe. For frozen cherries and blueberries, NCHFP also drops the Clear Jel to 1/4 cup per quart, or 1 3/4 cups for 7 quarts. That is a little less starch than the fresh-fruit row in the table, and it keeps a juicy thawed pack from turning into paste.
There is a second tested path from Ball that starts with thawed tart cherries, drains off juice, and cooks 4 cups of that juice with sugar and ClearJel before the fruit goes back in. Use one tested method all the way through. Do not blend the NCHFP water formula with the Ball juice formula in the same pot.
If you only have sweet cherries
Sweet cherries are safe to can in this style of filling because cherries are a high-acid fruit. The official quantities were written for sour fruit, though, so the sugar level will taste candy-sweet if you leave it untouched. You may reduce the sugar and keep the spices where you like them. Do not reduce the bottled lemon juice. Make one quart first, bake it in a small pie, and then scale the sugar for the rest of the crop.
Process Times, Headspace, and Why Jars Bubble Over
Pints and quarts get the same boiling-water time. At 0 to 1,000 feet, process 30 minutes. Add 5 minutes at 1,001 to 3,000 feet, 10 minutes at 3,001 to 6,000 feet, and 15 minutes above 6,000 feet. Start the clock only after the water returns to a full rolling boil with the jars in the canner. Water should cover the lids by at least 1 inch.
Leave a full 1 inch of headspace. Thick pie filling expands in the canner. If you pack to the rim, the gel will push out, coat the sealing surface, and leave you with siphoned jars that look full to the lid after they cool. Sealed jars that siphoned are still usable if the lid is vacuum-tight. Wash the sticky residue off the threads, store without the rings, and plan to use those jars first.
After processing, turn off the heat, wait 5 minutes, then lift the jars. Cool them 12 to 24 hours. Remove the rings, check the seals, label, and store in a cool, dark place. Quality is best within a year. A sealed jar remains safe longer than that if the lid stays down and the filling looks and smells normal when you open it.
What You Can Change and What You Cannot
Sugar and the optional cinnamon or almond extract are flavor. You can lower the sugar if the cherries are already sweet, or bump it if a test quart tastes sharp. You can also use a little less Clear Jel for a looser topping, down to about three-quarters of the listed amount. Do not add extra Clear Jel to force a stiffer set. Extra starch makes heat penetration harder, not safer.
Leave these alone:
- Bottled lemon juice amount
- Cook-type Clear Jel as the only canned thickener
- 1-inch headspace
- Water bath process time for your altitude
- Jar size limits in the tested recipe (pints or quarts)
Cornstarch, flour, and tapioca are fine in a pie you bake the same day and eat. They are not a substitute in a shelf-stable jar. They can break down in the canner, turn cloudy, and interfere with even heating. If you cannot find Clear Jel, can plain cherries in water or syrup instead, then thicken the fruit on the stove when you make the pie.
Honey, Splenda, and other sweetener swaps show up in blogs. They are not part of the tested NCHFP cherry pie filling formula. If you want a different sweetener, freeze the filling or cook it fresh.
How to Use a Quart Once It Is on the Shelf
Spoon one sealed quart into an unbaked 8- or 9-inch crust, dot with butter if you like, add a top crust or streusel, and bake until the filling bubbles in the center. Two pints do the same job if that is what you processed.
The filling is not only for pie. Warm a pint and pour it over ice cream, cheesecake, pancakes, or plain yogurt. Fold it into a coffee cake batter or use it as a hand-pie filling. If a jar is thicker than you want for a topping, stir in a spoonful of hot water after you open it. Do not thin jars before they are processed.
If a lid never sealed, refrigerate that jar and use it within a few days, or freeze the contents. Do not reprocess a thick pie filling unless you enjoy mushy cherries.
Frequently Asked Questions
Can you use cornstarch when canning cherry pie filling?
No. Extension guidance is clear that cornstarch, flour, and tapioca are not approved thickeners for canned pie filling. They clump, thin out after the jars cool, and can block heat. Use cook-type Clear Jel in the jar, or can plain cherries and thicken later.
Do I have to use sour cherries?
Sour cherries give the classic pie taste. Sweet cherries work if you cut the sugar and keep the lemon juice at the tested amount. Taste a single quart in a pie before you commit the whole box of fruit.
Why did my jars look empty of headspace after processing?
The gel expands in boiling water. That is normal. If the jars sealed, wash the rims, store them without rings, and use them. Next time, measure a generous inch of headspace and avoid a violent boil that sloshes water over the lids.
How do I keep Clear Jel from turning lumpy?
Whisk it into the sugar while both are dry. Add that mix to cold water or cold cherry juice, then heat, stirring constantly. Dumping Clear Jel into a hot liquid is how you get starch dumplings that never dissolve.
How long does home-canned cherry pie filling last?
Plan to use it within a year for the brightest flavor and color. A vacuum-sealed jar stored cool and dark is still considered safe after that if the lid is intact and the filling is not moldy, fizzy, or off-smelling.
Can I can a half batch?
Yes. Scale the NCHFP 1-quart column. Do not guess the Clear Jel or lemon juice. Those two ingredients control texture and acidity, and they do not scale by “a little extra for good measure.”
Bake the First Quart Before You Can the Rest
If this is your first year with a new cherry variety, stop after one quart. Bake that jar in a small pie, then decide whether the sugar, cinnamon, and almond extract need a nudge. The lemon juice and process time stay put. The flavor calls are yours.
A labeled row of quarts in the pantry is the whole point. On a night when nobody wants to pit anything, you pop a lid, tip the filling into a crust, and let the oven finish the work you already did.
