Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Make the sauce
In a chafing dish, melt the butter over medium heat.
Add the flour and chopped onion, cooking until the mixture is brown.
Stir in the strained tomato and cook until thick, stirring occasionally.
Cook the shrimp
Clean, wash, and drain the shrimp, then add them to the mixture.
Season with salt and pepper to taste.
Cover the dish, reduce heat, and simmer for 10 minutes, stirring occasionally.

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 and becomes tender as it cooks in the sauce.
- Flour
- Thickens the sauce together with the butter as it cooks.
- Strained tomato
- Forms the liquid base of the sauce and adds acidity and body.
- Butter
- Adds fat and richness and carries the flavor of the onion.
The step that matters
Cooking the flour until brown. Browning the flour and onion in butter builds nutty, deeper flavor and helps the later sauce thicken evenly. Stop too early and the sauce tastes raw and pasty; go too far and it turns bitter.
Swap the tomato
How well each one fits the dish's main ingredients (butter, shrimp, flour, onion, pepper):

Fit is the average pairing score against butter, shrimp, flour, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
