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

What each ingredient does

Shelled peas
Provide the main flavour and body, thickening the soup when rubbed through a strainer.
Butter
Adds richness and a smooth, silky texture to the finished soup.
Mint
Adds a fresh, aromatic flavour to the soup.

The step that matters

Creaming the butter with hot soup. Adding cold butter straight into hot soup can separate or leave greasy specks. Blending it first with a few spoonfuls of hot soup until smooth lets the fat emulsify evenly before it is stirred back in.

Swap the mint

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

  1. Parsleyfits better
  2. Tarragonfits about as well
  3. Thymefits about as well
  4. Mintthe original

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