When making a traditional Yorkshire pudding, self-rising flour, which contains baking powder, can cause the pudding to turn soggy and flat during baking. Yorkshire pudding is a type of puff pastry that is more dense and compact than a popover, which is typically light and fluffy.
The traditional Yorkshire pudding recipe consists of all-purpose flour, eggs, milk and a pinch of salt, baked in hot beef drippings or vegetable oil. The King Arthur Flour Company recommends substituting self-rising flour for all-purpose flour only when a recipe calls for it or when the recipe includes at least ½ teaspoon of baking powder per each cup of flour.
