What each ingredient does

Loaf sugar
Dissolves into the lemon juice to form a sweet syrup that balances the acidity.
Lemon juice
Provides the acidity and lemon flavour of the syrup.
Carbonate of soda
Reacts with the acidic syrup to release carbon dioxide, making the drink effervesce.

The step that matters

Stir in the carbonate of soda and drink while effervescing. Carbonate of soda reacts with the acid in the lemon syrup to release carbon dioxide gas. The fizz fades as the gas escapes, so the drink should be finished soon after mixing.
