A flexible jelly recipe, that can start with any amount of apples*. Sugar is added in ratios to amount of juice and cooked until it sets. I recommend boiling no more than about 7 or 8 cups of juice at a time per batch.
Cheeseclothmuslin or old (clean) cotton pillow case, for draining fruit
Prepare your apples by washing, removing the stems and cutting off the blossom ends. You can leave whole or cut in half. If your apples come from a wild tree (ie. not sprayed), you may want to cut in half to make sure the inside is good. That's what I did.
Place prepared apples into a large stock pot and add water, just until it just peeks through the top of the apples (if any of your apples are floating, you've got too much). Bring to a boil over high heat, then reduce heat and simmer, without stirring, until apples are softened, 10-15 minutes.
While fruit is simmering, place a large colander over a bowl and line with tripled-up cheesecloth, a piece of muslin or a cotton pillow case.
When fruit is tender, pour into prepared colander and leave to drain for 2-3 hours. RESIST THE URGE TO POKE, PRESS OR SQUEEZE the pulp to get more juice. It will make for a cloudy jelly. Just let gravity do it's work and discard the pulp when draining stops.
Measure out the amount of juice and make note of how many cups of juice you have (I got 3 cups of juice out of this basket of apples). Add the juice to a large pot and bring to a boil over high heat. Reduce heat to medium and simmer, stirring, for about 20 minutes, skimming off any foam, as necessary.
Meanwhile, measure out sugar. You'll need 3/4 cup of sugar for every cup of apple juice that you had. (So if you had 4 cups of juice, you'll need 3 cups of sugar). Place the sugar in a stainless steel or oven-proof bowl (or on a baking sheet, alternately) and pop into a 300° oven anywhere from 5-15 minutes, stirring it around a couple of times (time in the oven will vary depending on how much sugar/oven etc., so WATCH CLOSELY. It should be hot to the touch, but not so hot it starts to melt around the edges.).
When sugar is hot, remove from oven. Remove pot with apple juice from the heat. Stir in the hot sugar just until it is dissolved. Place the pot back on the heat and WITHOUT STIRRING, boil for 5-8 minutes, until jelly reaches 220° on a thermometer or passes the cold plate test*.
Ladle jelly into clean jars and leave with lids off until almost cool (without moving jars around). When jelly is almost cool, seal with lids. Let stand in a sunny window, undisturbed for 24 hrs. Wax and store.
*Cold Plate Test: Place a plate in the freezer before you start your jelly. Place 1 tsp. hot jelly on cold plate and freeze for 1 minute. Remove from freezer. Surface should wrinkle when edge is pushed with finger. If surface doesn't wrinkle, continue cooking and repeat test every few minutes.What to do if your jelly doesn't set: Hey, it happens and it can happen for any number of reasons. If you have left your jelly out for 24 hours and it didn't set, simply dump the contents back in to your pot and re-boil it until it sets (use a thermometer to cook to 220° F. or until it passes the cold plate test, as above). If you want to be super-sure it's going to set the second time, you could also consider adding a bit of commercial pectin.Be sure to read the "Cook's Notes" in the original post, for more tips, options, substitutions and variations for this recipe!
