Why it works: Parsley and lemon 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 ↓
Liver Sauce for Fish
Ingredients
Directions
Boil the liver of the fish.
Pound it in a mortar with a little flour.
Stir it into some broth, the liquor the fish was boiled in, or melted butter.
Add parsley, cayenne, and essence of anchovy (or soy or ketchup).
Bring to a boil.
Rub through a sieve.
Optionally, add lemon juice or diced lemon.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish liver
- Forms the thick, rich body of the sauce once pounded and sieved.
- Flour
- Thickens the liver mixture so the sauce holds its body.
- Broth or fish cooking liquor
- Thins the mixture to a pourable sauce and carries savory flavor.
- Butter
- Adds fat for a smooth, rich mouthfeel.
- Essence of anchovy
- Adds deep savory, salty flavor that rounds out the sauce.
The step that matters
Rub through a sieve. Pounded liver contains fibers and lumps that stay coarse unless forced through a sieve. Sieving gives the sauce its smooth, even texture.
