Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted cod
- Provides the main flesh and savoury flavour of the dish.
- Boiled potatoes
- Form the bulk of the mash and give it a soft, smooth body.
- Cream
- Adds moisture and richness to the mashed potatoes.
- Butter
- Adds fat for a silky texture and rich flavour.
- Boiled eggs
- Add body and a soft, creamy texture when chopped into the mixture.
The step that matters
Boil the cod until cooked but not breaking apart. Overcooking causes the proteins to tighten and the flakes to fall apart into a dry, stringy texture, while undercooking leaves the fish firm. Gentle heat keeps the flesh moist and intact for mincing.
