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

What each ingredient does

Rump roast
Provides the main body of meat, which becomes tender through long, moist cooking.
Flour
Stirred into the browned onion and fat, it thickens the cooking liquid into a gravy.
Canned tomatoes
Supply liquid and acidity that help build the braising sauce.
Lard
Fat that carries the browning of the onion and roast, adding savoury flavour.

The step that matters

Cover and boil briskly for about 3 hours. Boiling too hard or uncovered can reduce the liquid and scorch the bottom of the pot before the meat softens. Keeping the lid on and watching the pot closely helps the collagen in the roast break down into tender meat without burning.

Swap the onion

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

  1. Capsicumfits better
  2. Okrafits better
  3. Eggplantfits better
  4. Onionthe original

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