What each ingredient does
- Powdered bicarbonate of soda
- Reacts with the acid to release carbon dioxide, which creates the fizz.
- Powdered tartaric acid
- Reacts with the bicarbonate of soda to release carbon dioxide gas for the bubbles.
- Syrup
- Adds sweetness and flavor to balance the sharp acid.
The step that matters
Adding the tartaric acid last. Carbon dioxide forms as soon as the acid meets the bicarbonate and escapes quickly from a liquid, so the drink should be served right away to keep its fizz.
