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 ↓
Cauliflower Au Gratin
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the cauliflower
Trim and wash cauliflower.
Cook cauliflower in slightly salted water until tender.
Drain cauliflower and let cool.
Make the sauce
Melt 2 tablespoons butter in a small saucepan.
Stir in flour and cook for a minute.
Gradually add milk, stirring constantly.
Let the sauce boil for 10 minutes.
Season sauce with salt, pepper, and nutmeg.
Add 1½ ounces grated cheese to sauce.
Assemble and bake
Shape cauliflower and place it on a serving dish.
Spoon a tablespoon of sauce onto the dish.
Place cauliflower on top of sauce.
Carefully pour remaining sauce over cauliflower.
Sprinkle remaining cheese and breadcrumbs over cauliflower.
Dot with a few bits of butter.
Brown in a gas oven at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflower
- Forms the main body of the dish and becomes tender when cooked in salted water.
- Butter
- Enriches the sauce and adds fat for flavour and browning on the surface.
- Flour
- Thickens the milk into a smooth white sauce when cooked briefly with the butter.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats and boils.
- Grated cheese
- Melts into the sauce and browns on top, adding savoury flavour.
The step that matters
Gradually add milk, stirring constantly. Adding milk slowly while stirring keeps the flour evenly dispersed, so the sauce becomes smooth instead of lumpy as the starch thickens.
Swap the cauliflower
How well each one fits the dish's main ingredients (butter, flour, milk, cheese, pepper, nutmeg):
