    *Crème fraîche is sold at some supermarkets. If unavailable, heat 1 cup whipping cream to lukewarm (85°F). Remove from heat and mix in 2 tablespoons buttermilk. Cover and let stand in warm, draft-free area until slightly thickened, 24 to 48 hours, depending on temperature of room. Refrigerate until ready to use.
