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

What each ingredient does

Butter
Fat that browns to give a nutty, toasted flavor.
Vinegar
Adds acidity that sharpens the rich butter.
Parsley
Adds fresh, herbal aroma to the rich butter.

The step that matters

Cooking the butter until it turns brown. Butter's milk solids brown through Maillard reactions and caramelization, creating nutty flavor. They burn quickly once browned, turning bitter, so watch closely and stop as soon as it is a deep golden brown.

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.
