Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Forms the main body of the roll and provides the meat texture once slowly cooked.
- Sausage meat
- Adds fat and savoury flavour that spreads through the lean beef as it cooks.
- Stale bread crumbs
- Soak up juices and fat from the sausage, helping hold the filling together.
- Tomato ketchup
- Adds sweetness and acidity to the cooking liquid, deepening the flavour of the sauce.
The step that matters
Roll up the beef tightly and tie it securely. If the roll is loose, the filling can escape and separate during the long simmer. Tight rolling and firm tying keep the sausage and crumb layer inside the beef, so each slice holds together when cut and served.
Swap the onion
How well each one fits the dish's main ingredients (beef, meat, bread, pepper, flour, sauce, tomato):
- Capsicumfits better
