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

What each ingredient does

Round or sirloin steak
Provides the meat that becomes tender during long, slow cooking.
Onions
Soften and sweeten as they cook, adding moisture and flavour to the sauce.
All-purpose flour
Thickens the cooking juices into a smooth, rich gravy.
Butter
Adds fat and richness, carrying flavour through the dish.

The step that matters

Cook slowly with the dish covered. Low, slow heat with a tight cover lets the connective tissue in the beef break down gently while trapping moisture. Too much heat or an uncovered dish can dry the meat and stop the juices from thickening properly.

Swap the onion

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

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

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