Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat and rich flavour, and coats the shrimp.
- Shrimps
- Provide the main protein and the seafood flavour of the dish.
- Tomato ketchup
- Adds tomato sweetness and acidity to the stewing liquid.
- Lemon juice
- Adds acidity that brightens the flavour of the stew.
- Sugar
- Balances the acidity and savouriness of the tomato and lemon.
The step that matters
Stew gently for three minutes. Shrimp cook quickly and turn tough and rubbery when overcooked. A gentle simmer for a short time cooks them through while keeping them tender.
Swap the tomato
