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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil the cauliflower in salted water until tender, then divide it into small clusters.
Butter a deep baking dish and layer the cauliflower clusters in it.
Layer
Sprinkle each layer with butter, coarse sea salt, and black pepper.
Cover with grated Parmesan cheese and then with cracker crumbs.
Wet each layer with milk and repeat until the dish is filled.
Finish with a layer of crumbs dotted with bits of butter and dusted with cayenne pepper.
Bake
Bake covered at 350°F (175°C) for 30 minutes, then uncover and brown.

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 turns tender and soft when boiled.
- Parmesan cheese
- Adds savory, salty flavor and helps the top brown as it bakes.
- Cracker crumbs
- Forms a crisp, golden topping that contrasts with the soft layers below.
- Milk
- Adds moisture that keeps the layers from drying out as they bake.
- Butter
- Adds richness and helps the crumbs and surface brown.
The step that matters
Uncover to brown the top. Baking covered traps steam, which cooks the cauliflower through without drying it. Uncovering lets the surface dry out, so the crumbs and cheese can brown through the Maillard reaction, which creates flavor and color.
