and it took almost 3/4 of an hour - after it came to a boil - before the jelly sheeted on the back of a spoon. I checked the temperature of it and it was just barely over 200 and I read you have to get it above 220F for it to set right. What's the problem? Directions said 15 minutes! I didn't overcook it to that point, because it was dripping off the spoon like crazy up til then. Fine now.
