Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted fat that carries flavour and gives the sauce a rich, smooth body.
- Flour
- Thickens the butter and liquids into a light sauce that clings to the shrimp.
- Tomato sauce
- Adds acidity and savoury depth, colouring the sauce and balancing the richness of the butter.
- Shrimps
- Provide the main protein and mild sweetness, cooking quickly in the sauce.
The step that matters
Boil the sauce for one minute before adding the shrimp. Flour thickens only when it has been heated long enough to bubble, so the sauce needs a full minute of boiling to cook out the raw floury taste and reach its proper thickness before the delicate shrimp go in.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, sauce, onion, shrimp):
- Chivefits better
- Okrafits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, sauce, onion, shrimp. Candidates are from the same food group and used in at least 100 recipes.
