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

What each ingredient does

Onion
Browns in butter to add deep, savory flavor and sweetness to the gravy.
Butter
Carries the onion's browning and adds richness and fat to the gravy.
Flour
Thickens the broth into a smooth gravy when cooked with the fat.
Broth or stock
Forms the liquid base that gives the gravy its main savory flavor.

The step that matters

Frying the onion until dark brown. Browning develops deep flavors through the Maillard reaction and caramelization, so pale onions produce a flatter, less savory gravy. Stop before it burns, since scorched onion tastes bitter.

Swap the onion

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

  1. Shallotfits better
  2. Capsicumfits better
  3. Chivefits better
  4. Onionthe original

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