Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten to a froth, they add a light, airy texture to the punch.
- Rich sherbet
- Provides the sweet, fruity base that the other ingredients are folded into.
- Lemon or citron
- Its zest, grated over the sugar, adds aromatic flavor and brightness.
- Rum
- Adds spirited flavor and aroma to the punch.
The step that matters
Gradually stir the frothy egg whites into the sherbet. Adding the foamy whites slowly keeps their air bubbles from collapsing, so the punch stays light instead of turning dense or separating.
