For a richer flavor, use European-style heavy cream, which has a higher fat content. If your kitchen is warmer than 75°F (24°C), check the creme fraiche more frequently to prevent it from over-thickening or separating. If you don't have buttermilk, you can substitute it with 2 tablespoons of lemon juice or white vinegar mixed with enough milk to equal 1 cup. Let it sit for 5 minutes before using. Once made, Creme Fraiche will keep in the refrigerator for up to 2 weeks.
