How to make creme fraiche

It’s like magic to watch creme fraiche thicken right before your eyes! (That is, while you sleep.) All you need is 24 hours and a warm place, and you can make your own. It’s a nice way to use up leftover cream, or perfect if you can’t find creme fraiche at the store and have 1 day to wait. Here’s what you need to make creme fraiche:

1 cup heavy cream (with 18-20% fat content)1 tablespoon plain yogurt (Greek or regular)Clean container with a cover (preferably glass)

Stir the two ingredients together, then cover the container and place it in a warm place. After 24 hours, you’ll see the cream has thickened! It doesn’t have to be fully thick, because it will continue to thicken in the refrigerator. Voila: beautiful creme fraiche!

What makes the magic? Fermentation.

How does it all work? Here’s the basic scientific breakdown on what happens when you make creme fraiche:

Creme fraiche is a French version of sour cream, but it’s even richer and thicker. Creme fraiche has a higher fat content and a less tangy flavor than sour cream. This velvety cultured cream is used in many ways: as a creamy dip for veggies, for dolloping soups, or even a spoonful over fruit or a dessert. It doesn’t separate or curdle when heated, ideal for making creamy sauces. Here are some of our favorite ways to use it:
