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

What each ingredient does

Tartaric acid
Supplies the sharp, sour taste that gives the nectar its tang.
Lemon juice
Adds extra acidity and fresh citrus brightness.
Egg whites
Beaten whites add foam and a light, airy body to the drink.
Sugar
Provides sweetness that balances the sourness once dissolved.

The step that matters

Let the mixture cool slightly before adding the egg whites. Egg whites are heat-sensitive; if the liquid is too hot, the proteins can cook and set, losing the foamy, smooth texture the beaten whites are meant to give.

Swap the lemon
