Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon
- Provides the acidity that reacts with baking soda to release carbon dioxide bubbles.
- Baking soda
- Reacts with the lemon's acid to create the fizz that makes the drink effervescent.
- Pounded sugar
- Adds sweetness to balance the sharpness of the lemon juice.
The step that matters
Stir in the baking soda and drink immediately. Baking soda and acid react right away, releasing carbon dioxide gas. The bubbles escape from the liquid over time, so the drink loses its fizz if it sits. Adding the soda last and serving at once keeps it lively.
