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

What each ingredient does

Haddock
Forms the main body of the dish; its delicate flesh flakes as it cooks.
Strained tomato
Adds moisture and acidity, keeping the fish moist and building a sauce.
Flour
Coats the fish so the seasoning clings and the juices thicken slightly.
Onion
Adds aroma and mild sweetness to the tomato sauce as it cooks.

The step that matters

Cover the fish with strained tomato before the long cook. The tomato layer shields the delicate fish from direct heat and keeps it moist during the long bake. Fish proteins toughen and dry out when overcooked, so the tomato cover helps protect the texture over the two hours.

Swap the onion

How well each one fits the dish's main ingredients (haddock, pepper, flour, tomato):

  1. Capsicumfits better
  2. Spinachfits better
  3. Potatofits better
  4. Onionthe original

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