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

What each ingredient does

Sugar
Sweetens the punch and dissolves into the citrus juice to balance its acidity.
Egg whites
Whipped into the drink to add a light, foamy texture.
Champagne
Provides the sparkling liquid base and adds its own aroma.
Lemons
Supply acidity and aromatic oils from the rind and juice.

The step that matters

Dissolving the sugar in the citrus juice. Sugar dissolves best when given time to stand in the juice, which draws out moisture and softens the grains. Undissolved sugar leaves a gritty texture and uneven sweetness in the finished punch.

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.
