A lihapiirakka (in Finnish Lihapiirakka literally " meat pie") is an everyday Finnish dish sold in supermarkets and often available hot from street kiosks selling fast food. It is a form of savoury meat doughnut made from doughnut dough and filled with a mixture of minced meat and cooked rice and cooked by deep frying. It does not resemble a traditional English or American meat pie due to the use of doughnut mix and the fact that it is deep fried. They are usually bought ready cooked and are simply reheated in a microwave oven.
A larger and thicker form is also known as a Möttönen. Two Karelian variants are atomi and vety ("atom" and "hydrogen"), where vety contains ham and egg, but atomi only one of these.
Traditionally the pastry is eaten as whole. Newer way of eating is that the lihapiirakka is split and then filled further with a frankfurter or other type of sausage, or with kebab meat or some form of meat burger. Generally they are served with ketchup, mustard and a special cucumber relish (chopped cucumber and onion in a sweet base, similar to Bostongurka).
