Sour Cream
Sour cream is cream fermented with lactic acid bacteria into a thick, tangy dairy product, a staple cooling counterpoint to spicy, rich, or sweet dishes.
How to buy
Check the fat content, since full-fat sour cream holds up better in cooking without breaking than light or fat-free versions. Choose tubs without excess watery separation pooled on top.
How to store
Refrigerate tightly sealed and use within 1-2 weeks of opening. It's prone to curdling or separating if boiled directly, so stir it into hot dishes off the heat or at the very end of cooking. Freezing isn't recommended, as it separates badly.
Culinary profile
- Flavor
- Tangy and rich, with a cooling effect that balances heat and spice; milder and thicker than buttermilk, less nutty than crème fraîche.
- Texture
- Thick and smooth, dense enough to dollop and hold its shape, but easily stirred thin for dressings.
- Aroma
- A mild, tangy, clean lactic aroma from fermentation.
How to prepare
- Dolloped — Spooned over tacos, chili, or baked potatoes as a cooling finish.
- Whisked into dips — Blended with herbs or dry seasoning mixes into a quick party dip.
- Baked in — Added to cake and quick-bread batters for moisture and a tender crumb.
- Stirred in off heat — Mixed into stroganoff or goulash at the end of cooking to avoid curdling.
