Name: Russian Tea
Ingredients: Juice from 18 lemons; 2½ lbs sugar; ½ lb strong tea (like 'Golden Pekoe'); 3 cups water (for syrup); 1 quart cold water (for tea); Ice water (to make 7 quarts total)

Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Lemon and sugar 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

Sugar: Dissolves into the water to form a syrup that sweetens the drink.
Lemon juice: Adds acidity and bright citrus flavour that balances the sweetness.
Strong tea: Provides the tannins and deep flavour that give the drink its character.
