Lörtsy

Lörtsy is a thin, half-moon shaped pastry originally invented in Savonlinna, eastern Finland. It can be made with a variety of fillings; the most common ones are either a savoury meat filling or a sweet apple filling. A meat lörtsy contains a meat and rice filling similar to the Finnish meat pie. Street vendors may offer it with the same condiments as the meat pie, such as a pickled cucumber and chopped raw onion, and with an optional hot dog sausage. When served with condiments on the street, it is folded around them like a taco. The apple lörtsy contains a sweet apple jam, and resembles a jam doughnut.
