Khash is a type of food that is usually eaten in countries like Iran, Turkey, Iraq, and Armenia. It is made by cooking the feet and heads of cows, sheep, or goats for a very long time until the meat becomes very soft and tender.
Then, the bones and other parts that are hard to eat are removed and the liquid that was used to cook the meat is kept and served as a soup. People who eat khash usually add some vinegar, salt, or other seasonings to the soup to make it taste better.
Some people like to eat khash with bread or crackers, while others eat it with garlic or onions. It is usually eaten during the winter months because it is warm and filling.
So, in summary, khash is a food made from boiling the feet and heads of cows, sheep, or goats for a long time to make a soup that is often eaten with bread or crackers.
