Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Provides sharp acidity that gives the drink its tang and reacts with the bicarbonate.
- Bicarbonate of soda
- Reacts with the lemon's acid to release carbon dioxide, creating the fizz.
- Pounded sugar
- Adds sweetness to balance the lemon's acidity.
The step that matters
Add the bicarbonate of soda and drink while effervescing. The bicarbonate and acid react immediately to release carbon dioxide bubbles, and the gas escapes as the drink sits, so it should be drunk right away while still fizzing.
