Storage: Keeps in the fridge in an airtight container for up to 1-2 weeks. Stir before using.
Tips: Use fresh, high-quality heavy cream for the creamiest result. If your kitchen is cooler (<70°F), it may take closer to 24 hours; warmer speeds it up. For extra tang, use vinegar or let it sit longer.
Variations: Some add ¼ cup whole milk or 1-2 tablespoons buttermilk/yogurt as a starter for more culture, but this 2-ingredient version is the easiest and most foolproof.
Uses: Dollop on baked potatoes, tacos, chili, soups, or mix into dips, mashed potatoes, or baking recipes (like cakes or biscuits for tenderness).
Why it works: The acid curdles the cream slightly, thickening it into sour cream without heat.
This one's incredibly simple and satisfying—perfect for a quick homemade staple.
