Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black tea
- Provides the main flavor and the tannins that give the iced tea its body and slight bite.
- Sugar
- Adds sweetness and softens the tea's natural astringency.
The step that matters
Let the tea cool slowly before chilling. Cooling the tea gradually keeps it clear; chilling hot tea quickly can cause cloudiness as tea compounds precipitate.
Swap the lemon
How well each one fits the dish's main ingredients (black tea, sugar):
- Vanillafits better
- Orangefits better
- Lemonthe original
- Apricotfits about as well
Fit is the average pairing score against black tea, sugar. Candidates are from the same food group and used in at least 100 recipes.
