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

What each ingredient does

Flank steak
Forms the main protein, which becomes tender through slow simmering in liquid.
Drippings
Fat in the skillet that browns the steak surface, adding color and savory flavor.
Tomato
Provides the acidity and body of the sauce once heated and strained.
Butter
Adds richness and flavor to the sauce and helps it feel smooth.
Flour
Thickens the strained tomato into a sauce that clings to the steak.

The step that matters

Simmering until tender. Flank steak is lean, with tough muscle fibers. Long, gentle simmering in liquid breaks down connective tissue, so rushing it or boiling hard leaves the meat chewy.

Swap the tomato

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

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

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