Lihama Corn flour, custard powder, and baking powder are distinct ingredients with different uses in cooking and baking. Corn flour is a finely ground powder made from corn, primarily used as a thickening agent. Custard powder is a blend of starch, flavorings, and colorings, used to make custard and other creamy desserts. Baking powder is a leavening agent, containing a dry acid and a base, that helps baked goods rise.
