Why it works: Wine and brandy are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 2,427 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓

Make the custard base
Beat the yolks of the eggs until they are pale and thick.
Add boiling water, grated lemon rind, and lemon juice, sweetening to taste.

Combine and set
In a separate bowl, beat the egg whites to stiff peaks.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they cook.
- Egg whites
- Beaten to stiff peaks, they lighten the custard with airy structure.
- Lemon juice
- Provides the sharp acidity that defines the custard's flavour.
- Brandy
- Adds aroma and warmth to the lemon flavour.
The step that matters
Stir until thick as custard. Egg yolks thicken as they heat, but if the mixture gets too hot it can curdle or scramble. Gentle, constant stirring over moderate heat keeps it smooth.
Swap the lemon
How well each one fits the dish's main ingredients (egg, wine, brandy, sugar):
- Vanillafits better
- Apricotfits better
- Applefits better
- Lemonthe original
Fit is the average pairing score against egg, wine, brandy, sugar. Candidates are from the same food group and used in at least 100 recipes.
