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 ↓
Scalloped Prawns
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.
Make the sauce
Preheat the oven to 350°F (175°C).
Melt the butter in a saucepan over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring until thickened.
Season with salt and pepper.
Assemble and bake
Combine the Prawn meat with the sauce.
Transfer the mixture to a baking dish and top with breadcrumbs.
Bake for 20 minutes or until golden brown.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawns
- Provide the main protein and bulk of the dish.
- Butter
- Adds richness and fat that carries flavour through the sauce.
- Flour
- Thickens the milk into a smooth sauce that holds the prawns together.
- Milk
- Forms the liquid base of the sauce, setting into a creamy texture when thickened.
- Breadcrumbs
- Form a crisp, golden topping through browning in the oven.
The step that matters
Gradually add the milk, stirring until thickened. Adding cold milk all at once to hot roux can cause lumps. Adding it slowly while stirring lets the starch disperse evenly, giving a smooth sauce that thickens as it heats.
