>>It's a biscuit.
I guess this is just one of those things where, as civilized people, we're just going to have to agree that you're wrong. HHH
Actually, when I lived in Switzerland, I found the "biscuit" (that's a beesskwee, not a biskitt) distinction useful, because a biscuit is a subset of what in the US we would call cookies. To me there are two basic categories of cookies: chewy and yucky. In Switzerland, biscuit refers only to the second kind.
I love tiramisu, but can only eat so much. I can eat a near infinite amount of chaussons aux pommes though.
