One can use pasteurized cream for making butter however the quality and flavor will not be the same as using fresh cream. Though churning your own butter from store-bought cream will still be better than average store-bought butter. Avoid buying cream with additives. Butter is made from the cream that rises to the top of whole milk when it is cooled. This cream has a milk content of at least 30%. By agitating the cream the membranes surrounding the molecules are broken allowing the molecules to stick together. The simplest way to substitute buttermilk is to pour 1 Tbs. of vinegar into a 1 cup measure and then fill the rest of the measuring cup with milk. Then gently stir the mixture and let it sit for about 5 minutes. If you don’t have vinegar, lemon juice and cream of tarter also work as great buttermilk substitutions.
