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

What each ingredient does

Ox heart
Forms the main body of the dish, becoming tender with gentle simmering.
Dried flour
Coats the slices and thickens the liquid as it simmers.
Vinegar
Adds acidity that sharpens the flavour of the sauce.
Brown sugar
Balances the sharpness of the vinegar and adds depth of sweetness.
Onion
Adds aromatic flavour to the sauce as it cooks.

The step that matters

Simmer gently over low heat. Ox heart is a tough muscle meat. Gentle, low heat over a sustained period breaks down its connective tissue slowly, while a rolling boil would toughen and dry the surface.

Swap the onion

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

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

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