Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Bicarbonate of soda
Reacts with the citric acid to release carbon dioxide, which makes the drink fizz.
Citric acid
Supplies the acid that reacts with the bicarbonate of soda and gives the drink its sourness.
Pounded white sugar
Adds sweetness to balance the sourness of the citric acid.

The step that matters

Stir well and drink while effervescence occurs. The fizz comes from the reaction of bicarbonate of soda and citric acid in water, and carbon dioxide escapes quickly. Drinking promptly keeps the drink lively, so the effervescence is not lost.

Swap the lemon

Fit is the average pairing score against sugar, ginger, beer. Candidates are from the same food group and used in at least 100 recipes.
