3lbssour apples-preferably organicGranny Smith or Crabapple are good. The best apples will be green, sour and harder than a ripe apple
Water
Instructions
Wash apples and chop them into 1-2" pieces. Keep core, seeds, and skin with chopped apples.
Place in a large pan or preserving pan and add just enough water to cover the apples.
Cover the pot, bring to a boil and simmer gently for 40 minutes - 1 hour.
Line a colander with muslin or cheesecloth and place it over a large bowl.
Pour cooked apples into colander and allow the juice to drip through the colander. I place the bowl and colander in the refrigerator and let it drain overnight.
Pour the strained apple juice into a clean pan and simmer gently until thick and reduced by half. I stick a butter knife into the apple juice to get a gauge of the beginning depth of the juice.
Test the strength of your stock. Check the notes below.
Once reduced, you can either freeze it or water-bath can it in half-pint jars using the hot pack method. Leave 1/4” headspace and process for 10 minutes. Store in a cool dark place for up to 1 year.
Notes
Test your pectin stock strength by adding 1 teaspoon of the stock to 1 tablespoon of rubbing alcohol. Swirl the mixture and then let it set for 1 minute. If you can pick up the glob with a fork, then you have a strong stock. If you don't have 1 glob, but instead 2-3 smaller globs, continue to cook down your stock for a little bit. In general, 1 cup of Apple Pectin Stock and 2 cups of Sugar will help gel 3 lbs of low to medium pectin fruit for a good jam.
