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):
