Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- New milk
- Its proteins curdle when the citrus juice is added, and the curds carry away solids to clarify the liquid.
- Lemons
- Their juice adds sharp acidity that curdles the milk and balances the sweetness.
- Seville oranges
- Their juice adds acidity, and their thinly pared rinds add aromatic oils and bitterness.
- Double-refined sugar
- Adds sweetness that balances the acidity of the citrus and the bitterness of the rinds.
- Rum
- Adds alcohol, which carries the citrus aromas and helps keep the finished liquid stable.
- Brandy
- Adds alcohol and body, which carries the citrus aromas and helps keep the finished liquid stable.
The step that matters
Adding the citrus juice to the milk. The acid in the juice makes the milk curdle, and the curds must be left to form and settle so they can be strained out later. Adding the juice too gently or too little can leave the liquid cloudy and unclear.
