Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Whitefish
Forms the main body of the dish, becoming flaky and tender as it cooks.
Flour
Coats the fish, giving a light dusting that helps the surface hold its shape.
Tomatoes
Add moisture and acidity that flavour the fish as it steams in the bag.
Onion
Adds aromatic sweetness and savour as it softens during cooking.

The step that matters

Sealing the fish in the cooking bag. If the bag is not sealed tightly, steam escapes and the fish can dry out. A sealed bag traps moisture so the fish cooks gently in its own juices and the vegetables.

Swap the tomato

How well each one fits the dish's main ingredients (whitefish, pepper, flour, onion, parsley):
