These flavorful wafers, simply baked grated cheese, make a delightful accompaniment to soups or a sophisticated nibble to serve with drinks. As the only ingredient, the cheese matters here. Be sure to use imported Parmigiano-Reggiano (look for the name stenciled on the rind) and grate it yourself.
Make Ahead Tip: Store in an airtight container for up to 4 days.
