Today, October 13, 2014, is National Yorkshire Pudding Day. Yorkshire pudding is an English dish made from batter consisting of eggs, flour, and milk. The dish is usually served with roast meat and gravy and is a staple of the traditional British Sunday roast. It may also be served as a dessert. The exact origin of the Yorkshire pudding is, as yet, unknown. The first recorded recipe appears in a book in 1737. Yorkshire pudding is cooked by pouring a batter made from milk (or water), flour and eggs into preheated, oiled, baking pans, ramekins or muffin tins (in the case of miniature puddings). A basic formula uses 1⁄3 cup flour, 1⁄3 cup liquid, and 3 eggs.
