Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, acidity and flavour of the sauce.
- Butter
- Carries the aromatics and adds richness to the sauce.
- Flour
- Cooked with the butter to form a roux that thickens the sauce.
- Stock
- Adds liquid and savoury depth for stewing the tomatoes.
- Onions
- Build a sweet, savoury aromatic base for the sauce.
- Smoked ham
- Adds smoky, salty savour that flavours the sauce.
The step that matters
Cook the flour without browning. Cooking the butter and flour together for 10 minutes cooks out the raw starch taste and lets the roux thicken evenly. Browning would add a darker colour and nutty flavour that changes the sauce's intended character.
Swap the clove
How well each one fits the dish's main ingredients (tomato, butter, onion, carrot, ham, garlic, flour):
- Parsleyfits better
- Thymefits better
- Celeryfits better
- Clovethe original
Fit is the average pairing score against tomato, butter, onion, carrot, ham, garlic, flour. Candidates are from the same food group and used in at least 100 recipes.
