Using Baking Soda Paste

Make a baking soda paste.

Make a baking soda paste.
Combine about two tablespoons of baking soda with about one tablespoon (15 milliliters) of water. The mixture should not be too thin. If it sloshes about in the bowl you mixed it in, add some more baking soda to help it achieve a more paste-like texture. It also shouldn't be too thick. If the mixture is thick and dry, and doesn't adhere well to the fork or spoon you use to mix it, add some water to thin it out.
