i located the watermelon rind recipe today. i have a file folder for jams/jellies recipes, and it was in that. the recipe calls for pureeing the peeled and cubed watermelon rind, then you cook it/add sugar, cinnamon and pectin/can it. i'll make watermelon rind jelly again next year.how do you make jelly, jam, from water melon rind? I used to make jam out of every fruit imaginable, even quince.
