Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Lemon and Liver Sauce
Ingredients
Directions
Prepare the citrus
Pare off the rind of the lime or sour orange as thin as possible, avoiding the white part.
Remove all the white pith from the lemon and cut it into thin slices. Pick out the seeds and divide the slices into small squares.
Make the sauce
Add the lemon squares and a little minced peel to the prepared liver.
Combine with the melted butter and warm gently without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemon
- Adds sharp acidity and fresh citrus flavour that cuts through the richness of the liver and butter.
- Butter
- Adds fat and smooth richness, carrying flavour and giving the sauce a silky texture when melted.
- Lime or sour orange
- Its peel supplies aromatic citrus oils, adding fragrance and bright flavour to the sauce.
The step that matters
Warm gently without boiling. Boiling can make the melted butter separate and can toughen the liver proteins, leaving the sauce greasy and grainy rather than smooth.
