What each ingredient does
- Carbonate of potash
- Reacts with the citric acid to release carbon dioxide gas, which makes the drink fizz.
- Citric acid
- Reacts with the carbonate of potash to release carbon dioxide, and gives the drink its sharp, sour taste.
The step that matters
Pouring one tumbler into the other. The fizz comes from the reaction when the acid and carbonate meet, so the powders must be fully dissolved first. Pouring while the carbonate is still undissolved means less gas is released in the mixing step.
