Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Browns with the flour to add a nutty, toasted flavour and fat to the sauce.
- Flour
- Thickens the stock into a smooth sauce as it cooks with the butter.
- Stock
- Forms the liquid base of the sauce, carrying the other flavours.
- Mushroom catsup
- Adds savoury, umami depth to the sauce.
- Tomato catsup
- Adds sweetness and acidity for a tangy balance.
The step that matters
Browning the flour in the butter. The roux must be cooked long enough to lose its raw starchy taste and develop color, but not so long that it scorches and turns bitter. Stirring keeps it even.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, pepper, mushroom):
- Shallotfits better
- Spinachfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
