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, giving the cooking liquid a smooth, rich gravy flavour.
Flour
Its starch thickens the boiling liquid into a gravy that coats the asparagus.
Bread
Forms the toasted base that holds the asparagus and soaks up the gravy.

The step that matters

Thicken the gravy with a little flour. Flour needs to be whisked into the hot liquid and cooked through so it thickens smoothly without lumps or a raw, pasty taste. Its starch swells as it heats, so the gravy only thickens properly when the liquid is hot enough.

Swap the asparagus

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

  1. Shallotfits better
  2. Capsicumfits about as well
  3. Leekfits about as well
  4. Asparagusthe original

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