This is the traditional Swedish crispbread often served at Midsummer or Christmas together with herring and cheese (SOS - Sill, Ost, Smor). I prefer fennel as a spice, but you could try caraway or aniseed, or a mixture as well. Make sure the oven is as hot as possible. The hole in the middle is traditional, and necessary for the placing on the stick. If you don't have a Swedish roller, prick the breads everywhere with a fork before baking.
