I have made pepper jelly a couple of times in the past, but can't find my recipe right now (it's on an index card somewhere)...
But this recipe is very similar:
http://allrecipes.com/Recipe/jalapeno-pepper-jelly/detail.aspxI never used any food coloring in mine though...
used fresh Jalapeno's rather than the jared... and I used Cider Vinegar instead of white vinegar...
