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

What each ingredient does

White sugar
Provides the bulk of the sweetness and body of the syrup.
Egg whites
Coagulate as the syrup heats, trapping impurities so they can be strained out for a clear result.
Tartaric acid
Adds sharp acidity that balances the sweet syrup.
Baking soda
Reacts with the acid when stirred in, releasing carbon dioxide bubbles that make the drink fizz.

The step that matters

Bring the mixture to nearly boiling, then let it boil and strain immediately.. As the syrup heats, the beaten egg whites coagulate and gather impurities that rise so they can be strained away. Straining right after boiling keeps the syrup clear, and letting it sit or boil too long can cloud it or darken its flavor.

Swap the lemon
