Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salt butter
Fat that is browned in the pan to form the nutty, bitter-tasting base of the sauce.
Vinegar
Adds acidity that sharpens the rich, fatty butter and balances its flavour.
Sheep's brains
Main protein; its soft, delicate texture is the centrepiece of the dish.
Parsley
Contributes fresh, green aroma that cuts through the richness of the butter.

The step that matters

Heating the butter until nearly black. Butter solids brown and then burn quickly, so the butter must be watched closely. Stopping at the right colour gives a nutty flavour rather than an acrid, burnt taste.

Swap the parsley

How well each one fits the dish's main ingredients (butter, vinegar, pepper):

  1. Tarragonfits about as well
  2. Parsleythe original
  3. Thymefits less well
  4. Dillfits less well

Fit is the average pairing score against butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
