Shared aroma: isoamyl acetate (banana, pear).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Its milk proteins form the curds when acid is added, leaving liquid whey behind.
- Vinegar or lemon juice
- Its acid makes the milk proteins clump together, which starts the curdling.
The step that matters
Add the acid and stir gently. Acid causes milk proteins to clump into curds. Vigorous stirring can break the forming curds into fine particles that pass through the cloth and leave the whey cloudy.
