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 ↓
Fish Custard
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Flake the cooked fish and place it in a slightly buttered pie dish.
Sprinkle the fish with salt and pepper.
Make the custard and bake
In a bowl, beat the eggs and add the milk.
Pour the egg and milk mixture over the fish in the pie dish.
Bake for 30 minutes or until the custard sets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a soft, sliceable structure as they cook.
- Milk
- Forms the liquid base of the custard, keeping it moist and tender as it sets.
- White fish
- Provides the main flavour and body of the dish, held within the custard.
The step that matters
Baking until the custard sets. Egg proteins coagulate as they heat, turning the liquid into a firm custard. Underbaking leaves it runny, while overbaking can make it grainy, rubbery and watery as the proteins tighten and squeeze out liquid.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
