How the cold foam ratio works

Sweet cream cold foam uses two parts milk to one part heavy cream. The milk froths easily and the cream adds the body that keeps the foam floating. Classic cold foam skips the cream and relies on the protein in nonfat or 2% milk. The calculator scales whichever style you choose to your exact cup size.
