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 flavour and tannins that give iced tea its character.
- Cold water
- Slowly extracts flavour from the tea leaves without the bitterness of hot brewing.
The step that matters
Letting the tea stand. Steeping in cold water for 5 to 6 hours draws out flavour gradually. Stopping early leaves the tea weak, while steeping much longer can make it taste more bitter and astringent.
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.
