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

What each ingredient does

Steak
Provides the meat that becomes tender during the long slow simmer.
Flour
Thickens the cooking liquid into a richer, thicker sauce as it simmers.
Onions
Add sweetness and flavour that mellow into the sauce during simmering.

The step that matters

Frying the steak until crisp on both sides. Browning the meat creates deeper savoury flavour through the Maillard reaction. Pieces that are crowded or not dry will steam instead of browning, so the flavour and colour of the dish suffer.

Swap the onion

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

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

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