Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the sharp acidity and fragrant oils from the peel and juice.
- Fine sugar
- Adds sweetness and balances the sharpness of the lemon juice.
- Hot water
- Dissolves the sugar and draws flavour out of the steeped lemon rinds.
- Boiling milk
- Its proteins curdle with the lemon acid, and the jelly bag strains out the curds for clarity.
The step that matters
Mixing in the boiling milk. The milk must be added to the acidic lemon mixture so it curdles and the curds can be strained out. Adding it too gently or too early can leave the drink cloudy or uneven, so the jelly bag straining needs to follow promptly.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, milk):
- Vanillafits better
- Figfits better
- Peachfits better
- Lemonthe original
Fit is the average pairing score against sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
