Why it works: Cauliflower and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 687 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Cauliflower Au Parmesan
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Break the cauliflower into branches and wash them.
Boil the cauliflower in salted water until tender, but not too soft.
Coat and bake
Drain the cauliflower and dip each piece in melted butter, then in grated Parmesan cheese mixed with dry mustard, pepper, and salt.
Place the cauliflower neatly on a baking dish and pour a little more melted butter over it.
Bake in a 400°F (200°C) oven for five minutes and serve immediately.

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 becomes tender when boiled.
- Butter
- Adds richness and moisture, helping the coating stick and the surface brown.
- Parmesan cheese
- Melts and browns in the oven, forming a savory, crisp coating.
- Dry mustard
- Adds a sharp, pungent note that balances the richness of the cheese and butter.
The step that matters
Boil until tender but not too soft. Overboiling breaks down the cauliflower's cell walls, leaving it mushy, and it will soften further in the oven. Stopping when it is just tender keeps the florets firm enough to hold the coating.
Swap the cauliflower
