a new title (), a fundamental dish of Ukrainian cuisine that is served all around the country with several regional varieties, for example, the Chernihiv style nalysnyky are marked by their mushroom and cabbage filling. The most popular form of nalysnyky served in Ukraine is those stuffed with cottage cheese and served with sour cream. Nalysnyky, as well as mlyntsi, are also served for special occasions such as Masnytsya, which may originally have been a pagan festival that celebrated the end of winter and the arrival of spring (the round yellow pancake most likely symbolising the sun), but has for a millennium been the time for using up dairy products before the beginning of Great Lent. Nalysnyky can be formed out of mlyntsi in several different shapes, including; tubes, envelopes, and even triangles. Some recipes call for the stuffed mlyntsi to be placed in an oven-proof dish and cooked in an oven.
