Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Forms the rolled outer meat that becomes tender during long, moist cooking.
- Sausage meat
- Adds fat and savoury flavour that melts into the filling as it cooks.
- Stale bread crumbs
- Absorb the meat juices and fat, helping bind the filling and keep it moist.
- Flour
- Dredged on the outside, it helps the surface brown and thicken the cooking liquid.
- Tomato ketchup
- Adds sweetness and acidity that deepen the savoury, tangy flavour of the braising liquid.
The step that matters
Tie the rolls firmly before cooking. Loose rolls can open during the long simmer, letting the filling escape into the liquid. Firm rolling and tying keep the filling enclosed while the beef softens.
Swap the onion
How well each one fits the dish's main ingredients (beef, meat, bread, pepper, flour, sauce, tomato):
- Capsicumfits better
- Shallotfits better
- Potatofits about as well
- Onionthe original
Fit is the average pairing score against beef, meat, bread, pepper, flour, sauce, tomato. Candidates are from the same food group and used in at least 100 recipes.
