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 ↓
Cauliflower Au Gratin
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Cook the cauliflower
Boil the cauliflower until tender, then drain and place it upright on a serving dish.
Make the cheese sauce
In a saucepan, melt the butter, then whisk in the flour and gradually add the milk to make a sauce.
Season the sauce with salt, pepper, and cayenne, then stir in the grated cheese, reserving 1 tablespoon of cheese.
Bake and serve
Pour the cheese sauce over the cauliflower and sprinkle the reserved cheese on top.
Bake in a hot oven at 400°F (200°C) until nicely browned on top, then garnish with parsley.

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 holds its shape under the sauce.
- Milk
- Liquid base that, with the flour, thickens into a smooth sauce.
- Butter
- Fat that carries flavor and helps form a smooth roux with the flour.
- Flour
- Thickens the milk into a sauce by gelatinizing starch when heated.
- Cheese
- Melts into the sauce for richness and savory flavor, and browns on top.
The step that matters
Add the milk gradually to the butter and flour. Adding liquid slowly while whisking lets the flour starch disperse evenly, preventing lumps. A smooth base thickens evenly into a silky sauce instead of a grainy one.
Swap the cauliflower
How well each one fits the dish's main ingredients (milk, butter, flour, pepper, cheese):

Fit is the average pairing score against milk, butter, flour, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
