Why it works: Lemon and champagne work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 404 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Roman Punch
Ingredients
Directions
Freeze
Place the lemon ice, champagne, maraschino, and vanilla in a freezing pot surrounded by ice.
Freeze the mixture, stirring thoroughly with a spatula.
Finish
Gradually add the egg whites of Italian meringue paste while vigorously mixing.
If the mixture is too stiff, add a little more champagne to achieve the desired consistency.

Lemon and egg barely smell alike, yet cooks put them together in 44,316 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 whites
- Add airy structure and a light, foamy texture to the frozen mixture.
- Maraschino liqueur
- Adds sweetness and aroma, and keeps the mixture softer when frozen.
- Champagne
- Adds liquid and acidity, and can be added to loosen a mixture that is too stiff.
The step that matters
Gradually add the egg whites while mixing vigorously. Adding the meringue all at once can leave lumps and deflate its air bubbles. Gradual addition and vigorous mixing distribute the foam evenly, giving a light, smooth texture.
Swap the vanilla
How well each one fits the dish's main ingredients (lemon, champagne, egg):
- Orangefits better
- Raspberryfits better
- Pineapplefits better
- Vanillathe original
Fit is the average pairing score against lemon, champagne, egg. Candidates are from the same food group and used in at least 100 recipes.
