My boyfriend is looking for a type of cracker/cookie used in layered cakes/desserts he had as a child in either Switzerland or France. He says it was round, flat but wavy and bubbly, and not very sweet. I guessed pizzelli or some type of crepe, but he says it's something else. Any ideas?
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
