Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the oil and stock into a smooth gravy as the roux cooks.
- Vegetable oil
- Carries the flavor of the onion and forms the base of the roux with the flour.
- Vegetable stock
- Supplies the liquid that the roux thickens into gravy.
- Yeast extract
- Adds savory depth, contributing umami flavor to the gravy.
- Onion
- Adds aromatic sweetness and savory flavor as it browns in the oil.
The step that matters
Cooking the roux until it darkens. Cooking flour in fat until it darkens develops color and nutty flavor, but scorched flour turns bitter. Stir steadily and keep the heat moderate so the roux browns evenly before the stock is added.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, beef):
- Capsicumfits better
- Carrotfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against pepper, flour, beef. Candidates are from the same food group and used in at least 100 recipes.
