Why it works: Sherry and champagne share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 61 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Roman Punch
Ingredients
Directions
Prepare the ice
Ensure the ice is frozen hard.
Mix and serve
Just before serving, stir in the liquors and beat hard.
Add the stiffly beaten egg whites last.
The punch should be frothy and not frozen hard; it should almost pour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to foam, they give the punch a light, frothy texture.
- Lemon ice
- Provides the cold, sweet, tart base that the liquors are stirred into.
- Jamaica rum
- Adds strong flavour and alcohol, which lowers the freezing point so the punch stays slushy.
- Brandy
- Adds warm depth of flavour and alcohol that keeps the punch from freezing solid.
- Sherry
- Adds a rich, nutty flavour and extra alcohol to the blend.
The step that matters
Keep the punch frothy, not frozen hard. Alcohol lowers the freezing point of the mixture. If the punch freezes solid, it cannot be beaten into foam or poured, so it should stay slushy and almost pourable.
