The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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

Bicarbonate of soda
Reacts with the acid to release carbon dioxide, creating the fizz.
Tartaric acid or citric acid
Reacts with the bicarbonate to release carbon dioxide and gives the drink its sharp acidity.
White sugar
Adds sweetness to balance the acidity.
Jamaica ginger
Provides the characteristic spicy ginger aroma and flavour.

The step that matters

Keep the two powders separate until use. Bicarbonate and acid react as soon as they meet in water, releasing carbon dioxide. If they are mixed dry or dissolved too early, the fizz is lost before drinking, so each powder must be dissolved separately and the two solutions combined just before serving.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, ginger):

  1. Lemonthe original
  2. Orangefits about as well
  3. Limefits less well
  4. Vanillafits less well

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