ah. bad source. Most margarines have "buttery flavor" from some part of a dairy product. Kosher has some pretty amazing wiggle room. My rabbi allows Yoplait Yogurt with kosher geletain. One of my (Jewish)foodie alert sites noted that a couple kosher certification orgs allows get this: geletain made from PIGS. ewwww, eh?
this is the one we made: http://vegweb.com/recipes/sweets/73.shtml and it was DELICIOUS, thank you so much Ophelia!! It was sooo good!
