Ingredients
1 1/2 cups heavy cream
1/2 cup low-fat buttermilk, (1 percent to 2 percent)
Preparation
Pour cream and buttermilk into a 2 1/2-cup jar with a lid. Replace the lid, shake well, and allow mixture to rest at warm room temperature overnight. Refrigerate for at least 24 hours before using; the mixture will reach its optimal thickness after 4 or 5 days.
