To begin, peel, core, & slice your apples. Place the apples in a large bowl of water with citric acid or ascorbic acid to prevent oxidation as you prep all the apples.
Heat a large pot of water to boiling.
Drain the apples and blanch them in the boiling water for one minute. Work in batches.
As each batch blanches, scoop the apples out to a bowl. Do this with all the apples.
In a large, non-reactive pot, combine the sugar, water, apple juice, Clear Jel, cinnamon, and nutmeg.
Stirring continually (with a whisk), heat the mixture until it begins to bubble.
Add in the lemon juice and bring the mixture to a boil. Continue to stir briskly with a whisk. Boil for 1 minute and remove it from the heat.
Fold in the hot apples to combine.
Spoon the apple mixture into prepared, hot pint or quart jars. Leave a generous 1-inch head space.
Use a bubble wand to remove air bubbles. Add additional apple mixture if needed to maintain the head space.
Wipe the rims of the jars with a damp rag dipped in white vinegar.
Place a lid on the jar and secure it with a ring, finger tight.
Place the jars in your hot water bath canner or steam canner.
Process the jars for 25 minutes (Adjust for elevation, see article linked in the blog post above.)
Once the processing time is completed, turn off the heat and remove the lid of the canner. Let the jars rest for 5 minutes.
Remove the jars to a draft-free location that is lined with towels or a cooling rack.
Let the jars sit 12-24 hours, or overnight to cool completely.
Remove the rings, test the seals, and wash the jars if needed. Label the jars and store them in your pantry.
