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

What each ingredient does

Oysters
Provide the main flavour and tender texture when cooked gently until firm.
Flour
Thickens the milk-based liquid into a smooth, body-rich soup as the roux cooks.
Milk
Forms the creamy base of the soup and gives it its smooth, mild richness.

The step that matters

Boiling the oysters after adding them. Oysters turn rubbery and shrink when overcooked, so they should simmer only until their edges curl and they are just firm.

Swap the mace

How well each one fits the dish's main ingredients (oyster, flour, milk):

  1. Jalapenofits better
  2. Nutmegfits better
  3. Cinnamonfits better
  4. Macethe original

Fit is the average pairing score against oyster, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
