Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon juice
- Provides the main sour, bright flavor of the syrup.
- Granulated sugar
- Sweetens the syrup and helps preserve it.
- Citric acid
- Adds extra sourness and acidity to the syrup.
The step that matters
Let the mixture sit for 24 hours, stirring several times. Steeping lets the sugar dissolve fully and draws flavor from the lemon juice and rinds into the liquid. Stirring keeps the sugar and solids evenly distributed so the syrup tastes consistent.
