I having some friends over for dinner on Saturday and 2 are GF. My vision for dessert is homemade spumoni with some tuiles. I'm sure either of them would be happy eating the ice cream, but if there's a way I could make the tuiles GF, I'd like to try--especially since there's so little flour in tuiles in the first place. I don't want a big thick clunky cookie--I like the idea of something light and crispy. Could I just grind up some oats or use rice flour?
