Canning cinnamon apples means packing peeled slices in a cinnamon syrup, or packing them as a thickened pie filling, then processing the jars in a boiling-water canner. Which jar you get depends on the recipe you follow. Slices in syrup use the tested hot-pack method for canned apples: boil the fruit in syrup for 5 minutes, leave 1/2 inch of headspace, and process pints or quarts for 20 minutes at elevations up to 1,000 feet. A ready-to-bake filling is a separate tested recipe, thickened with cook-type ClearJel and acidified with bottled lemon juice, with 1 inch of headspace and a 25-minute process at the same elevation. Those two procedures are not interchangeable. Adding flour or cornstarch to either one is the change most likely to ruin the jar.
Decide Which Jar You Want to Open
Most searches for cinnamon apples are really a choice between two shelf-stable products.
Slices in cinnamon syrup are apple pieces in a pourable liquid. Open a jar for a warm side dish, oatmeal, pancakes, or a crisp. If you want pie later, thicken the liquid on the stove when you bake. This version follows the National Center for Home Food Preservation method for sliced apples, with cinnamon added to the syrup for flavor.
Cinnamon apple pie filling is already thickened. One quart is sized for an 8- to 9-inch pie. It uses the NCHFP apple pie filling recipe, which already includes cinnamon. The texture comes from ClearJel, not from a longer boil.
A third, less common product is spiced apple rings: crosswise rings cooked in a very sweet vinegar syrup with cinnamon and cloves, then processed for a shorter time. That is a pickled fruit, not the jar most people mean by cinnamon apples, and the published version is extremely sweet.
| Cinnamon apple slices | Cinnamon apple pie filling | |
|---|---|---|
| Texture in the jar | Slices in pourable syrup | Thickened filling |
| Thickener | None | Cook-type ClearJel only |
| Headspace | 1/2 inch | 1 inch |
| Process at 0–1,000 ft | 20 minutes | 25 minutes |
| Best use | Eating, baking after you thicken | Pie, cobbler, turnovers |
Apples That Stay in Slices
Firm, crisp apples hold their shape. Juicy fruit with some tartness tastes better after canning than a very sweet, mealy apple. Varieties that usually work include Granny Smith, Honeycrisp, Braeburn, Jonagold, Rome, Golden Delicious, and Stayman. NCHFP specifically lists Stayman, Golden Delicious, Rome, and similar firm apples for pie filling. If the fruit is low in tartness, that recipe calls for an extra 1/4 cup of lemon juice for each 6 quarts of slices.
Softer apples such as McIntosh and many Red Delicious break down in the jar. They are better as applesauce than as cinnamon slices.
Plan on about 2 3/4 pounds of apples per quart. A full canner load of sliced apples averages 19 pounds for 7 quarts, or 12 1/4 pounds for 9 pints. A 48-pound bushel yields roughly 16 to 19 quarts.
Set Up the Canner Before You Peel
Use a boiling-water canner with a rack, pint or quart jars, new flat lids, and bands. Wash jars and keep them hot. Start heating the canner so the water is ready when the jars are filled. Fruit has to go into the canner hot. A long pause between filling and processing is a common cause of seal failure and liquid loss.
Apples are a high-acid fruit, so a tested boiling-water process is the standard method. NCHFP also publishes a short pressure-canner process for plain sliced apples. It does not publish one for apple pie filling. Do not invent a pressure time for the thickened recipe.
To limit browning while you work, hold peeled slices in water with ascorbic acid: 1 teaspoon of pure ascorbic acid powder per gallon of water, or six crushed 500-milligram vitamin C tablets per gallon. Lemon juice in the holding water also slows darkening. Drain well before the fruit goes into the syrup. The holding liquid is not the canning liquid.
How to Can Cinnamon Apple Slices
This is the tested sliced-apple process with cinnamon added to the syrup. Do not raw-pack. NCHFP notes that raw packs make a poor-quality product, and uncooked slices are a frequent cause of siphoning because apples hold a lot of air.
Keep the color, then hot-pack. Wash, peel, core, and cut away bruises. Slice about 1/2 inch thick and drop the pieces into the ascorbic-acid water. Drain. For every 5 pounds of slices, add 1 pint of water or syrup. Boil 5 minutes, stirring so the fruit does not scorch.
Choose the syrup, then add cinnamon. Sugar is for flavor and texture, not for safety. Apples can be canned in water, very light syrup, light syrup, or medium syrup. For a 7-quart canner load, NCHFP’s syrup table is:
- Very light (about 10% sugar): 10 1/2 cups water and 1 1/4 cups sugar
- Light (about 20% sugar): 9 cups water and 2 1/4 cups sugar
- Medium (about 30% sugar): 8 1/4 cups water and 3 3/4 cups sugar
Heat the water and sugar together until the sugar dissolves. For cinnamon apples, stir ground cinnamon into that syrup, or add cinnamon sticks while it heats. A moderate starting point is 1/2 to 1 teaspoon of ground cinnamon per quart, or one stick per quart. Sticks leave a clearer syrup. Ground cinnamon tastes stronger and will settle. Dry spice can be adjusted for taste. Do not add butter, thickeners, or large amounts of any low-acid ingredient.
Up to half the sugar in a syrup may be replaced with light corn syrup or mild honey. Heavy syrup is allowed for tart fruit, but it is sweeter than most people want once cinnamon is in the jar.
Fill and process. Pack hot slices and hot liquid into hot jars, leaving 1/2 inch of headspace. Run a bubble tool around the inside, adjust the level, wipe the rims, and apply lids. Process pints or quarts in a boiling-water canner:
- 0–1,000 feet: 20 minutes
- 1,001–3,000 feet: 25 minutes
- 3,001–6,000 feet: 30 minutes
- Above 6,000 feet: 35 minutes
The timer starts when the water returns to a full boil. If the boil stops, bring it back and start the full time again. When the time ends, turn off the heat, remove the lid, and wait 5 minutes before lifting the jars. That short rest reduces siphoning. Cool jars undisturbed for 12 to 24 hours.
How to Can Cinnamon Apple Pie Filling
Use this only if you want a thickened filling. NCHFP’s tested quantities are:
| Ingredient | 1 quart | 7 quarts |
|---|---|---|
| Blanched sliced apples | 3 1/2 cups | 6 quarts |
| Granulated sugar | 3/4 cup + 2 tbsp | 5 1/2 cups |
| Cook-type ClearJel | 1/4 cup | 1 1/2 cups |
| Cinnamon | 1/2 tsp | 1 tbsp |
| Cold water | 1/2 cup | 2 1/2 cups |
| Apple juice | 3/4 cup | 5 cups |
| Bottled lemon juice | 2 tbsp | 3/4 cup |
| Nutmeg, optional | 1/8 tsp | 1 tsp |
The published cinnamon level is mild. Dry spices may be increased for a stronger cinnamon flavor. Do not change the ClearJel, bottled lemon juice, or process time to make up for a spice change.
Wash, peel, core, and cut slices 1/2 inch wide. Hold them in ascorbic-acid water. Blanch in batches: 6 cups of slices in 1 gallon of boiling water, boiled for 1 minute after the water returns to a boil. Drain and keep the fruit hot.
Mix sugar, ClearJel, and cinnamon with the cold water and apple juice. Cook over medium-high heat, stirring, until the mixture thickens and bubbles. Add the bottled lemon juice and boil 1 minute, stirring constantly. Bottled juice is required here because its acidity is standardized. Fold in the hot drained apples at once.
Fill hot jars immediately, leaving 1 inch of headspace. Remove bubbles, wipe rims, and apply lids. Process pints or quarts:
- 0–1,000 feet: 25 minutes
- 1,001–3,000 feet: 30 minutes
- 3,001–6,000 feet: 35 minutes
- Above 6,000 feet: 40 minutes
ClearJel is the thickener this recipe was tested with. Instant ClearJel, flour, cornstarch, tapioca, and arrowroot are not substitutes. They can break down or thicken too much, which interferes with heat moving through the jar.
Why the Times and Headspaces Differ
Headspace is empty room at the top of the jar, not a guess. Slices in syrup need 1/2 inch so the vacuum can form without pulling out too much liquid. Pie filling expands and traps air around the fruit, so the tested headspace is 1 inch.
Processing time is the minutes at a full boil, adjusted for elevation because water boils at a lower temperature as elevation rises. A 20-minute process that is correct at sea level is not correct at 5,000 feet. Look up your elevation before you fill jars, not after the canner is loaded.
Floating Fruit and Liquid Loss
Apples float, and some liquid loss is common even in a correct process. The fruit is porous. Air left inside the slices expands, pushes liquid out, and leaves fruit at the top of the jar. Under-blanching, a raw pack, trapped bubbles, a boil that is too hard, and lifting jars the moment the timer ends all make this worse.
A sealed jar that lost some liquid is still usable if it was processed for the full time. Fruit above the liquid may darken. An unsealed jar is not shelf-stable. Refrigerate it and use it soon, or reprocess it with a new lid within 24 hours for the full time.
After 12 to 24 hours, remove the bands, check that each lid is concave and does not flex, wash the jars, and label them with the contents and date. Store in a cool, dark place. Home-canned fruit is best used within a year. Refrigerate after opening.
Changes That Break the Recipe
Safe flavor changes are small. Cinnamon, nutmeg, and similar dry spices can move up or down. Sugar in the slice syrup can be reduced, or the fruit can be packed in water. Sugar in the pie filling can also be adjusted for taste because the acid and the process, not the sugar, make that recipe shelf-stable.
Unsafe or untested changes are larger. Do not add flour, cornstarch, or instant ClearJel. Do not cut the bottled lemon juice in the pie filling. Do not use half-gallon jars, skip the hot pack, or shorten the time because the apples looked soft. Do not can a butter-and-sugar stovetop “cinnamon apples” recipe as written. Those skillets are for eating now, not for a boiling-water canner.
If a family recipe has no processing time, no headspace, and no acid measurement, treat it as a refrigerator or freezer recipe unless you can match it to a current tested process from NCHFP or your cooperative extension service.
How to Use the Jars
Slices in syrup can be warmed and served as they are, or drained and folded into oatmeal, yogurt, or a pancake batter. For a pie, drain off some liquid, then thicken the rest on the stove with the starch you prefer. Pie filling can go straight into a crust. One quart fills one 8- to 9-inch pie. It also works as the fruit layer in a cobbler or turnover.
Taste a jar before you commit a whole canner load to a spice level. The first batch is the useful test: same apples, same syrup, two cinnamon amounts, processed the same way.
Questions People Ask After the First Batch
Can the apples be left unpeeled? The tested sliced-apple and pie-filling directions say to peel. Peels add bitterness and a tougher texture after processing. They are not a safety issue by themselves, but they are outside the quality the process was written for.
Why did the syrup turn brown? Holding slices too long without ascorbic acid, using mealy fruit, and overcooking the hot pack all darken the jar. Cinnamon also colors the syrup. A tan syrup with intact slices is normal. Gray fruit usually means the holding step was skipped.
Can these be frozen instead? Yes. Pie filling and syrup-packed slices both freeze well if you are not set on a shelf-stable jar. Cool the mixture first, leave freezer headspace, and use within several months for best texture. Freezing avoids processing questions, but it does not replace a tested canning process if the jars are going into a pantry.
Is a sealed jar with fruit touching the lid safe? If the process, headspace, and seal were correct, contact with the lid does not by itself make the jar unsafe. Quality is the issue. Next time, hot-pack fully, debubble, and use the rest in the canner after the timer ends. Regular-mouth jars also keep slices under the shoulder better than wide-mouth jars.
