What is the difference between regular flour and pastry flour?
Regular flour (white or whole wheat) is milled from hard red wheat and has a higher gluten content. It is excellent for baking bread and other yeast-risen baked goods. Pastry flour (white or whole wheat) is milled from soft white wheat and has a lower gluten content. It is excellent for baked goods using baking powder or baking soda as leavening agents. It should not be used for baked goods where yeast is used.
