Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Release moisture and browning compounds that add savory, earthy depth to the sauce.
- All-purpose flour
- Thickens the broth into a smooth sauce that coats the linguine.
- Vegetable broth
- Provides the liquid that forms the sauce base and carries the flavor.
- Onion
- Softens and sweetens as it cooks, building the savory base of the sauce.
- Bell peppers
- Add sweetness and a tender, mildly crisp texture to the sauce.
The step that matters
Cooking the flour before adding the broth. Stirring the flour constantly for a minute cooks off its raw starchy taste and helps it blend smoothly, so the sauce thickens without lumps.

Fit is the average pairing score against onion, garlic, pepper, mushroom, shiitake, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
