Pepper Jelly

Directions

1. 1
   ["Cut the apples into eighths - do not remove the cores or the seeds, you need these to supply pectin.", "Slice the lemon - the whole lemon, do not discard the rind, pith, or seeds.", "Place the apples, jalapenos, red bell pepper, plums, cranberries, and lemon in a large stock pot with the vinegar and water. Bring to a boil, then reduce heat to medium-low and simmer for 30 minutes.", "Strain the apple mixture through a very fine sieve or a jelly bag. If you want a clear jelly, do not press down on the mixture or squeeze the bag. If you don't mind a cloudy jelly, you can press or squeeze all you like.", "Let the mixture drain for at least 30 minutes or as long as overnight, if you like. After the mixture has finished straining, measure out 6 cups of juice. If you don't have 6 cups of juice, add water to the juice to make 6 cups.", "If you have more than 6 cups of juice, freeze it to use later. Do not try to make more than the amount called for in this recipe, or you may not be able to get the jelly to set.", "Place 3 small saucers in the freezer - you will use these to check the set of the jelly.", "Pour the 6 cups of juice into a preserving pan. If you do not have a preserving pan, use the widest pan you have. The wider the pan, the more quickly moisture will evaporate from the mixture, and this is what you want when you are making jelly or jam.", "Add 4 1/2 cups sugar and the butter to the juice in the pan (the butter is to reduce foaming). Bring to a boil over high heat, stirring to dissolve the sugar.", "Cook over medium-high heat for 20 minutes.", "After 20 minutes of cooking, check the set (it may take up to 30 minutes of simmering over medium high heat for the jelly to reach the set stage - it depends on what kind of pan you are using and how high of heat you are using).", "Use the cold plate test to check set: take the pot of jelly off the heat (if you don't remove the jelly from the heat while you check the set it could over-cook and become rubbery or hard, if the jelly is indeed already set) .", "Place a drop of the jelly mixture on one of the saucers you've kept in the freezer, & place the plate back in the freezer for 1 minute. After 1 minute, take the saucer out of the freezer and nudge the drop of jelly with your finger. If it \"wrinkles\"" when you nudge it with your finger it is done. If the jelly is not set
