How much butter is needed to substitute for shortening in bread recipe?

When using butter instead of shortening in a bread recipe, you will typically use 1:1 substitution ratio. This means that you will use the same amount of butter as you would shortening. For example, if a recipe calls for 1 cup of shortening, you would use 1 cup of butter in its place.

However, it's important to note that butter and shortening have different properties and can affect the texture and flavor of the final product. Butter has a higher water content than shortening, so using butter may result in a slightly denser bread with a more pronounced flavor. Additionally, butter can brown more easily than shortening when baking, so you may need to adjust the baking time or temperature to prevent over-browning.
