Popovers are an American version of the English Yorkshire pudding. The differences are, popovers are larger and contain butter in the batter. Yorkshire puddings, usually served with prime rib, do not contain butter, but a teaspoon of the beef drippings is added to each cup before pouring the batter in. They are both traditional and delicious! Savory popovers are made with black pepper and cheese added to the batter.
Let cool slightly.
