Can paste food coloring be substituted for liquid color in baking?

Yes, you can substitute paste food coloring for liquid food coloring in baking. However, since paste food coloring is more concentrated, you will need to use less of it.

A ratio of 1:4 is a good starting point, meaning that you would use one part paste food coloring to four parts water. So, for example, if you wanted to use 1 teaspoon of liquid food coloring, you would only need to use ¼ teaspoon of paste food coloring.

You may also need to adjust the amount of water you add to your recipe to compensate for the extra liquid in the paste food coloring.

It's important to make these adjustments cautiously and gradually, as too much paste food coloring can make your baked goods bitter or alter their texture.

Because of this, it is advisable to start with a small amount and increase it gradually until you achieve the desired color. Always remember to do a preliminary trial of your recipe with the paste food coloring before making a larger batch.
