What each ingredient does
- Carbonate of soda
- Reacts with the lemon juice's acid to release carbon dioxide, creating the bubbles and fizz.
- Fresh lemon juice
- Supplies the acid that reacts with the carbonate of soda, and adds tart flavour.
The step that matters
Serve immediately. The fizz comes from carbon dioxide released by the acid-base reaction, and it escapes from the liquid over time, so the drink loses its effervescence if it waits.
