Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cauliflower Au Gratin
Ingredients
Directions
Prepare the cauliflower
Boil the cauliflower until tender, then drain and squeeze out excess water.
Make the sauce
In a small saucepan, melt the butter over medium heat.
Stir in the flour and cook until smooth and well combined.
Gradually add the cold water, stirring until the sauce is smooth and thickened.
Remove from heat and stir in the cream, salt, and cayenne.
Add 1 ounce of grated Parmesan to the sauce and mix well.
Assemble and brown
Place the cauliflower on a serving dish, pour the sauce over it, and sprinkle with remaining cheese.
Brown under a broiler until the cheese is melted and golden.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflower
- Forms the bulk of the dish and becomes tender after boiling, giving the gratin its body.
- All-purpose flour
- Thickens the butter and water into a smooth sauce as its starch swells when heated.
- Parmesan cheese
- Melts into the sauce and browns under the broiler, adding savory flavor and a golden top.
- Butter
- Adds richness and fat, and forms the base of the roux with the flour.
- Cream
- Adds richness and smooths the sauce's texture.
The step that matters
Cooking the flour into the butter and cold water sauce. Flour must be cooked briefly in the butter so its raw taste fades, and the cold water must be added gradually while stirring so starch granules hydrate evenly and the sauce thickens without lumps.
Swap the cauliflower
How well each one fits the dish's main ingredients (parmesan cheese, butter, flour, cream, pepper):
- Spinachfits better
- Asparagusfits better
- Potatofits better
- Cauliflowerthe original
Fit is the average pairing score against parmesan cheese, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
