Yorkshire pudding is a baked pudding that’s made from a batter consisting of eggs, flour, milk or water and typically served with beef. This is a very common side dish in the UK but it also has an American version which you may know as popovers!
Both use the same batter, and the only difference is that popovers are baked in individual molds and coated with butter, whilst yorkshire pudding is traditionally cooked in beef drippings using the pan a piece of beef has previously been roasted in.
