Hönökaka is a classic Swedish flatbread with a light, almost cake-like texture. It's made with a combination of milk, butter, white flour, rye flour, sea salt, yeast, ljus sirap (light syrup), and hjorthornssalt. The final ingredient gives the flatbread its fluffy and light texture – hjorthornssalt was originally made from deer antlers, but nowadays ammonium carbonate is used instead.

The dough is left to double in size, and it's then kneaded and flattened before being pricked with a kruskavel (a knobbly rolling pin) and baked in the oven. Once done, it's recommended to serve hönökaka warm with cheese, jams, honey, butter, or pickled herrings on the side.
