Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rare roast beef
- Provides the main protein; it is only warmed through in the sauce, so it stays tender.
- Stewed or canned tomatoes
- Supply the body, acidity and most of the sauce's liquid.
- Beef gravy or stock
- Adds savoury depth and extra liquid to the tomato base.
- Onion
- Adds aromatic sweetness and flavour once softened and browned in butter.
The step that matters
Stir in the beef and heat until hot. The beef is already cooked, so it only needs to warm through. Prolonged boiling toughens thin slices and dries them out, so keep the heat gentle once it is added.
Swap the onion
How well each one fits the dish's main ingredients (butter, tomato, beef, sauce, pepper):
- Capsicumfits better
- Potatofits about as well
- Onionthe original
- Carrotfits about as well
Fit is the average pairing score against butter, tomato, beef, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
