What is "Yorkshire pudding"?

Yorkshire pudding is a classic British dish that is made from a batter of eggs, flour, and milk or water. The batter is poured into a hot and greased baking dish and baked in the oven until it is puffy and golden brown. Yorkshire pudding is often served as a side dish to a roast beef dinner, and is known for its crispy and airy texture. It can also be served with gravy or as a base for other dishes, such as toad in the hole or filled with meat and vegetables as a savory pastry. Yorkshire pudding is a staple of British cuisine and is enjoyed by people of all ages.
