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

What each ingredient does

Haddock or whiting
Forms the main body of the dish, cooking gently inside its stuffing and baking tin.
Oatmeal
Absorbs moisture and binds the stuffing so it stays moist during baking.
Hard-boiled eggs
Add body and richness to the stuffing as they bind with the butter and oats.
Butter
Adds richness and moisture to the stuffing, and browns in the black butter sauce.
Flour
Thickens the black butter sauce as it cooks and toasts in the hot fat.
Lemon juice
Adds acidity that brightens the stuffing and the finished black butter sauce.

The step that matters

Heating the butter for the black butter. Butter solids darken quickly once the fat gets very hot, so it can pass from nutty brown to burnt in seconds. Watch it closely and stop heating as soon as it turns dark.
