Brands vary, so check the package for conversion instructions. When using Better Than Bouillon, we add 1 teaspoon of bouillon concentrate (paste) for every 1 cup of water. (Note: This uses slightly less paste than their package would suggest, but we find it plenty flavorful and salty at these levels). If using a bouillon cube, we usually use 1 cube for every 2 cups of water—but again, check the package as brands vary.
