Cream of Tartar - Controls the pH of egg whites and results in increased volume, stability and more uniform texture of the finished products.
Meringue – Our favorite frosting additive to top off bath bombs! The egg whites give the frosting body and also helps it to harden (which is why it’s frequently used in royal icing). The SLS makes bubbles – so really you’ll end up with a Bubble Bath Bomb. Using an electric mixer is the easiest way to make a smooth fluffy frosting – but you can also achieve great frosting with a whisk and some elbow grease!
