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, with flesh that flakes and turns opaque as it cooks.
Butter
Adds fat and richness, carrying flavor and keeping the fish moist as it cooks.
Parsley
Adds fresh, green aroma that brightens the buttery sauce.

The step that matters

Cook the haddocks in the butter sauce until done. Fish proteins set quickly and become dry and tough when overcooked. Cook gently only until the flesh turns opaque and flakes easily with a fork, since it keeps cooking briefly after leaving the pan.
