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

What each ingredient does

Shoulder steak
Provides the meat, which becomes tender during the long slow simmer.
Flour
Thickens the cooking liquid into a rich sauce as it heats.
Onions
Add sweetness and savoury depth as they soften into the sauce.
Butter or dripping
Carries the heat for frying and adds richness and browning to the steak.

The step that matters

Simmer below boiling point. A gentle simmer keeps the meat tender and prevents the flour-thickened sauce from scorching or breaking, while a hard boil toughens the muscle fibres and can cause the sauce to catch on the pan.

Swap the onion

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

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

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