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
Prepare
Boil the cauliflower until half cooked, then cut it into pieces and place them in a pie dish.
Boil the milk, adding the seasoning, ½ oz. of the butter, and a pinch of nutmeg.
Thicken the milk with the wholemeal flour mixed in a little cold milk or water.
Assemble and bake
Stir in the cheese and pour the sauce over the cauliflower.
Sprinkle the breadcrumbs on top, cut the remaining butter into small pieces, and place them over the breadcrumbs.
Bake for 20 minutes to 1 hour, or until the cauliflower is soft.

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 soft and tender during baking.
- Milk
- Forms the liquid base of the sauce, which thickens and carries the other flavours.
- Wholemeal flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Cheese
- Melts into the sauce and adds richness and savoury flavour.
- Butter
- Adds fat and richness to the sauce and helps the breadcrumb topping brown.
- Dried breadcrumbs
- Form a crisp, golden topping as they toast in the oven.
The step that matters
Thickening the milk with flour. Flour mixed into hot milk without first being blended smoothly in cold liquid forms lumps, because starch granules clump before they can disperse. Mixing it with cold milk or water first lets it thicken the sauce evenly.
