Kasha

In English, kasha usually[a][b][c] refers to the pseudocereal buckwheat or its culinary preparations. In Eastern European cuisine, kasha can apply to any kind of cooked grain. It can be baked but most often is boiled, either in water or milk, and therefore the term coincides with the English definition of 'porridge', but the word can also refer to the grain before preparation, which corresponds to the definition of 'groats'. Kasha is eaten widely in Belarus , the Czech Republic (kaše), Lithuania (košė), Poland (kasza), Romania and Moldova (cașa), Russia (каша), Slovakia (kaša), Slovenia (kaša), Kazakhstan, and Ukraine (каша), where the term, besides buckwheat, can apply to wheat, barley, oats, millet, rye and even rice. Kasha has been an important element of Slavic diet for at least 1,000 years. This English-language usage probably originated with Jewish immigrants, as did the form קאַשי kashi (literally translated as "porridges"). As an Ashkenazi-Jewish comfort food, kasha is often served with onions and brown gravy on top of farfalle, known as kasha varnishkes. Kasha is a popular filling for knishes and is sometimes included in matzah-ball soup.[citation needed]
