Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the main citrus flavour and acidity, with rind adding aromatic oils.
- Loaf sugar
- Adds sweetness to balance the sharp acidity of the lemon.
- Water
- Serves as the base liquid and carries the lemon and sugar flavours.
The step that matters
Peel the lemons thinly, avoiding the white pith. The white pith is bitter and releases bitter compounds into the drink, so only the thin yellow rind should be removed.
