Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Drippings
- Provide fat for cooking the flour and carrying flavour into the sauce.
- Flour
- Thickens the sauce as it cooks with the fat and liquid.
- Tomatoes
- Supply acidity, body and colour to the sauce.
- Beef
- Provides the main meat and is only warmed through briefly.
The step that matters
Adding the chopped beef. The beef is already cooked and rare, so it only needs brief heat. Cooking it too long toughens the meat and dries it out, so it should go in at the end.
Swap the tomato
How well each one fits the dish's main ingredients (flour, onion, beef):
- Chivefits better
- Leekfits better
- Okrafits better
- Tomatothe original
Fit is the average pairing score against flour, onion, beef. Candidates are from the same food group and used in at least 100 recipes.
