Discover the secret to authentic French crème fraîche by making it at home! The French secret weapon for silky sauces, dreamy desserts, and swoon-worthy soups. Make this recipe for your kitchen adventures!
Add 3 tablespoons cultured buttermilk. Stir gently, no whisking frenzy, just a calm swirl.
Cover loosely with a cloth held on with an elastic or a string tied around the top.
Leave at room temperature (around 70°F/21°C) for 12–24 hours. Check: it should be thickened and slightly tangy. If my kitchen is cold I place my jar in the oven with just the oven light on.
Stir, add the lid, and refrigerate. Voilà! Authentic crème fraîche!
Notes
Always use pasteurized cream, not ultra-pasteurized, it cultures better.
Always us a non-metallic spoon to stir or serve, as cultured food can react with metal.
Stir gently; overmixing can break the texture, and you don't want to fill it with air bubbles.
Taste daily while culturing, stop when tangy enough for your palate. But 12-24 hours should be sufficient.
Crème fraîche too thin? Strain it through a cloth for a few hours. But don't throw out the liquid, as it can be used in other ways, like baking.
If your kitchen is chilly, wrap the jar in a tea towel, or, as I do, place it in the oven with the light on.
Use less buttermilk for a thinner result and more for a firmer finish.
