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

What each ingredient does

Heart
Forms the main meat and becomes tender with long, moist cooking.
Broken bread
Absorbs liquid and gives the stuffing body and a soft texture.
Fat
Browns the surface, adding colour and savoury flavour.
Onion
Adds aromatic sweetness and moisture to the bread stuffing.

The step that matters

Simmer until tender. Heart is a tough, muscular meat that needs long, gentle, moist cooking to break down its connective tissue. Rapid boiling can toughen the surface and leave the centre firm, so keep the water at a gentle simmer.

Swap the onion

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

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

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