Crème Fraîche, a soured cream that’s slightly less sour than store-bought sour cream, is easy to make at home with the Anova Sous Vide Precision Cooker. You just need heavy cream, buttermilk, and a canning jar. It takes some time, but it’s worth the wait. This creme fraiche can be used in savory applications, or sweet ones, like with fresh berries.

Ingredients

• 2 cups heavy cream
• 6 tablespoons buttermilk

Preparation

1. Set the Sous Vide Precision Cooker to 105°F (40°C).
2. Seal the cream and buttermilk in a canning jar.
3. Place the jar in the water bath and set the timer for 12 hours.
4. Cover the water bath with plastic wrap to minimize water evaporation.
5. Add water intermittently to keep the jar submerged.

Finishing Steps

1. When the timer goes off, remove the jar from the water bath.
2. Transfer to an ice bath to cool.
3. Refrigerate for up to two weeks.
