Thanks ladies.

I am seeing some recipes that say to boil 15 minutes rather than 10. I assumed Ocean Spray would know best, but maybe not. Alton Brown does caution against boiling for too long, or else the pectin will break down. BTW he sets his in a can so it has ridges.

So the upshot is that I need to experiment more with longer boiling times.

At any rate, I've now been asked to find a low sugar version for Christmas, which was something I'd been wondering about for the sake of several family members with diabetes or pre-diabetes. There are plenty of recipes out there that use juice, honey, maple syrup, etc. rather than granulated sugar, and just a few that use sugar-substitutes like Splenda.

p.s. cranberry sauce on waffles is EXCELLENT.
