Sweetened potato casserole (Finnish imelletty perunalaatikko) is a traditional Finnish dish from Kymenlaakso eaten elsewhere in Finland at Christmastime. It is prepared by letting puréed potatoes mixed with wheat flour stand at a temperature of around 50°C (122°F). The amylase in the flour will start to break down the potato’s starches to shorter carbohydrate chains that is sugars. The temperature cannot exceed 75°C (167°F) otherwise the amylase molecules will break down.
