Why it works: Red wine and rum share more aroma than cooks usually use. They rank in the top 3% of all ingredient pairs, and 23 recipes mention both. Both carry eugenol, which smells clove, spicy. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)

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.

Fit is the average pairing score against milk, red wine, orange, rum, brandy, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
