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

What each ingredient does

Butter
Adds fat and richness, and carries flavour into the base.
Flour
Thickens the liquid into a smooth, body-rich base when cooked with the fat.
Vegetable stock and pulp
Supplies the main liquid and vegetable flavour, and the pulp adds body.
Milk
Adds creaminess and mild sweetness to the finished soup.

The step that matters

Gradually add the vegetable stock, stirring and cooking until thick.. Adding liquid slowly while stirring keeps the flour dispersed and prevents lumps. Cooking the mixture lets the starch swell and thicken the base evenly.

Swap the white pepper

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. White pepperthe original

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