TL;DR
No buttermilk at home? Mix milk with lemon juice or vinegar, wait 10 minutes, and keep cooking.
Ingredients
- 250 ml milk
- 1 tablespoon lemon juice or light vinegar
How to make it
- Pour the milk into a measuring cup.
- Stir in the lemon juice or vinegar.
- Let it sit for 10 minutes.
- Use it like buttermilk in pancakes, cakes, biscuits, or marinades.
Why it works
The acid lightly thickens the milk and adds the tang many recipes expect. In batters with baking soda, that acidity also helps the mixture rise properly.
Good to know
This is a practical baking and marinating substitute. It will not taste exactly like real buttermilk as a drink, but it saves the recipe when the carton is missing.
