The oldest traditional pasties usually had a rye crust, but the North Karelian and Ladoga Karelian variants also had wheat alongside of rye to improve the baking characteristics of the available rye breads. The common fillings of this era were barley and talkkuna. The 19th century first introduced potato and buckwheat as new fillings, and later due to trade, also rice and millet.
Nowadays in the most familiar and common recipe the pasties are made from a thin rye crust with a filling of rice. Butter, often mixed with boiled egg (egg butter or munavoi), is spread over the hot pasties before eating.
