Start by peeling, coring, and slicing your apples into even pieces. This can be done manually or with the help of an apple slicer. Make sure to remove any bruised portions.
In a large pot, combine the sliced apples, granulated sugar, brown sugar, lemon juice, cinnamon, nutmeg, salt, and water. Stir gently to combine all the ingredients. Cook over medium heat for about 15-20 minutes until the apples are tender.
In a separate small bowl, combine cleargel with a few tablespoons of water to create a slurry. Slowly pour the slurry into the pot while continuously stirring the apple mixture. Cook for an additional 2-3 minutes until the filling has thickened. Remove from heat.
Follow safe canning instructions and process jars for 25 mins. Times will depend on altitude.
