Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shrimp
- Provides the main protein, which firms and turns opaque as it cooks in the sauce.
- Flour
- Browned in the fat, it thickens the liquid and adds a nutty, toasted flavor to the sauce.
- Tomatoes
- Add acidity, moisture and body, forming the base of the sauce as they break down.
- Onion
- Softened in the lard, it adds sweetness and savory aroma to the sauce base.
- Lard
- Carries the flavor of the aromatics and provides fat for browning the flour.
The step that matters
Browning the flour. Flour cooked in fat must brown to a deep color for flavor and thickening. Pulling it too early leaves a raw, pasty taste, while scorching it gives a bitter burnt flavor. Stir constantly over medium heat.
Swap the onion
How well each one fits the dish's main ingredients (shrimp, tomato, flour, pepper, parsley):

- Onionthe original
Fit is the average pairing score against shrimp, tomato, flour, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
