Ukrainian cuisine has developed over centuries based around farming staples like rye, wheat and barley. Meals are divided into casual and festive, with special dishes cooked for holidays that often had religious significance. Influenced by the widespread use of stone ovens, Ukrainian food is known for dishes that are cooked, stewed or baked like borscht soup, varenyky dumplings, holubtsi stuffed cabbage rolls, and various breads, meats, kasha and sweets. Ukrainians are also renowned for their hospitality and have opened many restaurants serving their national cuisine.
