Crème fraîche always comes in plastic tubs and is ridiculously expensive, so I decided to learn how to make my own. Here are the ingredients I used:
- 1 pint (2 cups) heavy cream
- 1/2 cup buttermilk (also homemade)
Mix together heavy cream and buttermilk in a glass jar.
Cover with a cloth (I used a cloth napkin) and let sit in a warm place until thickened, 12-24 hours. I put mine in the oven since it has a pilot light.
After 24 hours, mine looked like this:
Give it a stir and put it in the fridge. After mine had been in the fridge for a while, it was even thicker:
It looks like sour cream, (and tastes similar) but there’s a difference. Sour cream is milk, cream, thickeners and gums. Crème fraîche is cream thickened with a souring agent (in this case, buttermilk). Crème fraîche is not as thick as sour cream, although mine turned out really thick this time. If you like it thinner don’t leave it to culture as long as I did.
