Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Provides sweetness and body to the syrup.
- Tartaric acid
- Supplies sharp acidity that gives the drink its tang and reacts with bicarbonate of soda to fizz.
- Egg whites
- Add foam and body to the syrup, giving a lighter texture.
- Bicarbonate of soda
- Reacts with the acid to release carbon dioxide, producing fizz.
The step that matters
Stir in the bicarbonate of soda. Bicarbonate of soda reacts with the tartaric acid to release carbon dioxide, which makes the drink fizz. Adding it too early, before serving, lets the gas escape, so the drink goes flat. Add it last, just before serving.
