Flour mixtures are blends of flour, liquid, and other ingredients used to make baked goods. They are classified as batters or doughs depending on their consistency. Batters contain more liquid than doughs. Common batters are pour, drop, and high-ratio cake batters. Common doughs are soft doughs for biscuits and bread, and stiff doughs for piecrust. Basic mixing methods include creaming, muffin, pastry, and one-bowl methods. Gluten development is important and controlled through flour selection, shortening, liquid, and mixing time. Proper preparation of pans and following baking instructions are also essential for success.
