What each ingredient does
- Lemon peel
- Carries aromatic oils that give the syrup its lemon fragrance.
- Lemon juice
- Supplies the main liquid and the tart, bright citrus flavour.
- Citric acid
- Adds extra sourness, sharpening the flavour of the syrup.
- Plain syrup
- Provides sweetness and body to balance the sourness of the citrus.
- Soda foam
- Adds fizz and a light, effervescent texture.
The step that matters
Add the soda foam last. Carbonation escapes quickly when liquids are warmed, agitated or left standing. Adding the soda foam after straining and sweetening helps keep the fizz and light texture in the finished syrup.
