Lemon Syrup
Ingredients
Directions
Prepare
Grate the rinds of 6 lemons into a bowl.
Juice 12 lemons and mix the juice with the grated rind.
Make the syrup
In a saucepan, bring 1 quart of fine syrup to a boil until it is almost caramelized.
Strain the lemon juice and rind through a fine sieve into the syrup before it caramelizes.
Boil the mixture for 3 to 4 minutes until it becomes a fine syrup.
Remove from heat and let it stand for a short time.
Bottle
Pour the warm syrup into bottles, cork them, and tie bladders over the corks.

What each ingredient does
- Lemons
- Juice adds sharp acidity and the grated rind adds aromatic citrus oils.
- Fine syrup
- Provides the sweetness and body that balance the lemon's sourness.
The step that matters
Strain the lemon into the syrup before it caramelizes. Sugar darkens and turns bitter once it caramelizes past the syrup stage. Adding the lemon juice and rind while the syrup is still pale keeps the flavour bright and clean instead of burnt-tasting.
