Why it works: Butter and milk 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 ↓
Whiting Au Gratin
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Clean and prepare the whiting fish.
In a pan, melt butter and add breadcrumbs, stirring until golden.
Assemble and bake
Place the fish in a baking dish, season with salt and pepper.
Pour milk over the fish and top with the breadcrumb mixture and grated cheese.
Bake for 20-25 minutes until the fish is cooked through and the top is golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whiting fish
- Forms the main body of the dish, cooking through gently in the milk.
- Butter
- Carries fat for browning the breadcrumbs and adds richness.
- Breadcrumbs
- Toast to a golden crust that contrasts with the soft fish beneath.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a crisp surface.
- Milk
- Provides moisture that gently poaches the fish and forms a creamy base.
The step that matters
Toasting the breadcrumbs in butter. Stirring until golden browns the crumbs through the Maillard reaction, which adds flavour. Pulling them too early leaves a pale, bland topping, and letting them burn gives a bitter taste.
