Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil of lemon
- Provides the main bright lemon aroma and flavour.
- Oil of orange
- Adds a rounder citrus aroma that supports the lemon flavour.
- Citric acid
- Adds sourness that balances the sweetness of the syrup.
- Syrup
- Supplies the sweetness and the bulk of the liquid.
The step that matters
Fully incorporating the oils. Citrus oils do not dissolve in water-based liquids, so they can float or clump if not mixed thoroughly first. Combining them with the citric acid and mixing well before adding to the syrup helps distribute the flavour evenly.
Swap the orange
How well each one fits the dish's main ingredients (lemon, syrup):
- Orangethe original
- Limefits about as well
- Raspberryfits less well
- Vanillafits less well
Fit is the average pairing score against lemon, syrup. Candidates are from the same food group and used in at least 100 recipes.
