Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Boiled Codfish—salt
Ingredients
Directions
Prepare
Soak the codfish in lukewarm water overnight or for several hours, changing the water several times.
About one hour before dinner, place the codfish in cold fresh water and set it over the fire.
Cook
Let it come to a boil or just simmer for 15 minutes, but do not let it boil hard.
Serve
Remove the codfish from the water, drain it, and serve with egg sauce or sliced cold boiled eggs on top, with drawn butter or cream gravy poured over.

Pepper and egg barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- The main protein, which turns firm and flakes into tender pieces when gently simmered.
- Butter
- Drawn butter adds richness and a smooth, moist coating that carries flavor over the fish.
- Eggs
- Egg sauce or sliced boiled eggs add richness and a creamy texture alongside the fish.
The step that matters
Keep the water at a gentle simmer, not a hard boil. Vigorous boiling forces the fish proteins to contract and tighten, which toughens the flesh and breaks it into ragged pieces. A gentle simmer cooks it evenly while keeping the flakes intact.
