I love making jellies. I love grapefruit and I thought, well why can't you make Grapefruit Jelly? So I looked around and this was the best recipe I could come up with, through looking and ammending. I had one of my sons friends try it, (who by the way hates grapefruit) and he absolutely loved it and took the jar home. Very good, made from store bought 100% juice. (yes I cheated) Everyone Loves This Jelly ! ! ! Surprised me! I just made it to try and say I did. lol Turns out its a favorite of most who tried it! Yes I like it too!
