Why it works: Cauliflower and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,113 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. 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
Preheat the oven to 400°F (200°C).
Remove the leaves from the cauliflower and boil it until tender.
Make the sauce
In a saucepan, heat the milk and whisk in the flour, salt, and pepper until smooth.
Assemble and bake
Pour the milk mixture over the cauliflower in a baking dish.
Sprinkle the grated cheese on top.
Return to the oven and bake until the cheese is browned.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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 when boiled, giving the gratin its body.
- Milk
- Forms the liquid base of the sauce, adding moisture and creaminess.
- Flour
- Thickens the milk into a smooth sauce as it is whisked in.
- Grated cheese
- Melts and browns on top, adding flavour and a golden crust.
The step that matters
Whisking the flour into the hot milk. Flour added to hot liquid can clump if not whisked well. Whisking it smooth before it thickens keeps the sauce even and free of lumps.
Swap the cauliflower
How well each one fits the dish's main ingredients (milk, flour, pepper, cheese):
- Capsicumfits better
- Potatofits better
- Spinachfits better
- Cauliflowerthe original
Fit is the average pairing score against milk, flour, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
