Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Salt Fish Soufflé
Ingredients
Directions
Prepare the base
Pare the potatoes and boil for 30 minutes.
Drain the water and mash the potatoes very fine.
Mix the mashed potatoes thoroughly with the fish.
Add butter, seasoning, and hot milk.
Beat 2 eggs well and stir into the mixture.
Bake and brown
Heap the mixture into a serving dish and place in the oven for 10 minutes.
Beat the whites of the remaining 2 eggs to stiff peaks, add ¼ teaspoon salt, then fold in the yolks.
Spread the egg mixture over the fish dish and return to the oven to brown.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed starch that forms the soft body of the dish.
- Eggs
- Set and bind the mixture, and the whipped whites lift it into a soufflé-like top.
- Salt fish
- Provides the main savoury flavour and salty character of the dish.
- Butter
- Adds richness and fat, softening texture and aiding browning.
- Milk or cream
- Adds moisture and makes the mashed potato mixture smooth and loose.
The step that matters
Beating and folding the egg whites. Whites must be beaten to stiff peaks and folded gently so the air they hold is not lost. Deflated whites produce a flat, dense top instead of a light, risen crust.
Swap the potato
How well each one fits the dish's main ingredients (fish, milk, egg, pepper, butter):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits less well
- Chivefits less well
Fit is the average pairing score against fish, milk, egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
