Buttermilk
Tangy, creamy, lightly sour, and dairy-rich.
Lens analyzedButtermilk is a cultured dairy liquid with tangy acidity used for pancakes, biscuits, marinades, dressings, and baking lift.
Where it comes from
Traditional buttermilk was the liquid left after churning butter; modern grocery buttermilk is usually cultured milk with a similar tang.
Varieties — Cultured liquid buttermilk, low-fat buttermilk, and powdered buttermilk differ in convenience and texture.
It is central to Southern baking and fried chicken, and appears anywhere tangy dairy helps tenderness.
Buying it
Choose refrigerated cultured buttermilk and check the date. Powdered buttermilk is useful for occasional baking.
Storing it
Keep refrigerated and shake before using. Use by the date or shortly after if it smells cleanly tangy, not spoiled.
Keeps about 14 days in the fridge.
Out of buttermilk? Good swaps
- Milk plus lemon juice — Acidifies milk for baking but lacks cultured body.
- Plain yogurt thinned with milk — Good for marinades and batters.
