The flavor team

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 lemon 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

Loaf sugar
Provides sweetness and body to the syrup.
Tartaric acid
Adds sharp acidity and reacts with baking soda to create fizz.
Egg whites
Coagulate gently when warmed, helping trap impurities so the liquid clears.
Baking soda
Reacts with the acid to release carbon dioxide, producing effervescence.
Essence of lemon
Adds a bright lemon aroma.

The step that matters

Stirring in the baking soda and drinking at once. Baking soda reacts with tartaric acid to release carbon dioxide, which gives the fizz. That gas escapes quickly from a stirred glass, so the drink should be served and drunk right away while still effervescing.

Swap the lemon

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

  1. Vanillafits better
  2. Raisinfits about as well
  3. Lemonthe original
  4. Datesfits less well

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