Makes 1 cup

INGREDIENTS

• 1 cup heavy cream
• 1 tablespoon live-culture yogurt (homemade or store-bought)

DIRECTIONS

1. In an impeccably clean glass jar, mix the cream and yogurt well.
2. Cover with a paper coffee filter secured with the jar lid ring or a sturdy rubber band.
3. Put on the counter at room temperature, protected from being disturbed. (Inside a cold oven is a good spot – just take care not to turn it on!) Leave for 12 to 24 hours (the longer, the thicker).
4. Cap with a secure lid and refrigerate for use up to 1 to 2 weeks.
