Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the peel and juice that give the syrup its bright, sharp citrus flavour.
- Loaf sugar
- Sweetens the syrup and helps draw flavour out of the lemon peel and raisins.
- Raisins
- Add sweetness and body, with extra fruit flavour as they soak in the liquid.
