What each ingredient does
- Bicarbonate of soda
- Reacts with the citric acid to release carbon dioxide, creating the fizz.
- Citric acid
- Reacts with the bicarbonate of soda to release carbon dioxide and gives the drink its sour taste.
- White sugar
- Sweetens the drink and balances the sourness of the citric acid.
The step that matters
Drink while effervescence continues. The fizz comes from carbon dioxide gas escaping as the bicarbonate and citric acid react in solution. Once the gas has escaped, the fizz is gone, so the drink should be consumed promptly.
