Syrup of Lemons
Ingredients
Directions
Make the syrup
Combine lemon juice and sugar candy in a saucepan.
Heat gently until the sugar dissolves, skimming off any foam until the surface is clear.
Add the thin-cut lemon peel and simmer gently for a few minutes.
Strain and store
Strain the mixture through a flannel cloth.
Once cool, bottle and cork it tightly, then store in a cool place.

What each ingredient does
- Sugar candy
- Provides sweetness and body, dissolving into the juice to make a thick syrup.
- Fresh lemon juice
- Supplies the sour lemon flavour that forms the base of the syrup.
- Lemon peel
- Adds aromatic lemon oils that scent and flavour the syrup while it simmers.
The step that matters
Skimming the foam while the sugar dissolves. Foam is made of impurities and air that would cloud the syrup and spoil its look. Removing it while heating gently keeps the syrup clear and clean-tasting.
