Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shrimps
- Provide the main protein, which turns opaque and firm when cooked through.
- Tomato catsup
- Adds sweetness, acidity, and a tomato flavor that coats the shrimp.
- Butter
- Adds richness and fat, giving the sauce a smoother, rounder mouthfeel.
The step that matters
Boil the shrimps until cooked. Shrimp turn from translucent to opaque and firm when done. Overcooking makes the flesh tough and rubbery, while undercooking leaves it unsafe to eat.
Swap the tomato
How well each one fits the dish's main ingredients (shrimp, butter, pepper):
- Capsicumfits better
- Potatofits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against shrimp, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
