Ingredients
Directions
Make the syrup
Combine lemon juice and sugar in a saucepan over gentle heat.
Stir until the sugar dissolves and skim off any foam until the surface is clear.
Add the thin-cut lemon peel and let it simmer gently for a few minutes.
Strain and bottle
Strain the mixture through a flannel cloth.
Once cool, bottle and cork it tightly, then store in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Provides the sharp acidity and lemon flavour that defines the syrup.
- Lump sugar
- Adds sweetness and body, and helps preserve the syrup once it is dissolved.
- Lemon peel
- Adds aromatic lemon oils and fragrance to the syrup.
The step that matters
Skim the foam. Foam is made of proteins and impurities that rise as the syrup heats. Skimming until the surface is clear keeps the syrup clean, bright and free of cloudiness in the bottle.
