Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Loaf sugar
Sweetens the punch and draws out flavor from the citrus rinds as it stands.
Egg whites
Whipped into the punch to add a light, foamy texture.
Champagne
Provides the sparkling liquid base and adds acidity and aroma.
Lemons
Supply acidic juice and fragrant oil from the rinds for flavor.

The step that matters

Letting the mixture stand overnight. Sugar pulls oils and flavor from the citrus rinds and juice over time, so skipping the rest leaves the punch thin and less aromatic.

Swap the orange

How well each one fits the dish's main ingredients (lemon, sugar, champagne, egg):

  1. Orangethe original
  2. Raspberryfits about as well
  3. Vanillafits about as well
  4. Pineapplefits less well

Fit is the average pairing score against lemon, sugar, champagne, egg. Candidates are from the same food group and used in at least 100 recipes.
