Crème fraîche can do anything sour cream does, more elegantly — serve it with caviar, drizzle on tacos, or dollop on berries. In fact, it’s better than sour cream because it doesn’t break at high temperatures: whisk a little into simmering sauces and soups to add tangy richness.

Ingredients

  • Buttermilk
  • Heavy cream, the best you can find, not ultra-pasteurized

    Preparation

    1. In a bowl, whisk together 1 part buttermilk with 8 parts of heavy cream. (For example, 1/4 cup buttermilk to 2 cups cream.) Cover the bowl and leave it at room temperature for 12 hours to 2 days, until it thickens and separates. Whisk together and transfer to a container; refrigerate, tightly covered.
