So far, the best things I've tried have been:
Pamela's GF Pancake Mix
Udi's White Bread (needs to be toasted)
Arepas (south American corn/cheese cakes)
Estrella Daura (beer)
Gluten Free Girl and the Chef's Pizza Dough recipe (really their flatbread cracker recipe)
I've been told that King Author's GF Brownie Mix is good but have yet to try it.
PLEASE. Use this thread to list any GF retail products that you think are superior. I'm tired of being burned.
