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
- Tea
- Provides the main flavour; brewing it stronger keeps the drink bold after it is diluted by ice.
- Sugar
- Adds sweetness that balances the tea's natural bitterness and the lemon's acidity.
- Lemon juice
- Adds acidity that brightens the flavour and sharpens the tea.
- Cracked ice
- Chills the drink and dilutes it slightly as it melts, softening the strong tea.
The step that matters
Brew the tea stronger than usual. Melting ice dilutes the drink as it sits, so tea brewed at normal strength can taste weak and watery. Extra strength gives the flavour room to survive the dilution.
Swap the lemon
How well each one fits the dish's main ingredients (tea, sugar):
- Vanillafits better
- Peachfits about as well
- Lemonthe original
- Orangefits less well
Fit is the average pairing score against tea, sugar. Candidates are from the same food group and used in at least 100 recipes.
