Cauliflower Au Gratin

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Cook the cauliflower

  1. Boil the cauliflower until tender, then drain and place it upright on a serving dish.

Make the cheese sauce

  1. In a saucepan, melt the butter, then whisk in the flour and gradually add the milk to make a sauce.

  2. Season the sauce with salt, pepper, and cayenne, then stir in the grated cheese, reserving 1 tablespoon of cheese.

Bake and serve

  1. Pour the cheese sauce over the cauliflower and sprinkle the reserved cheese on top.

  2. Bake in a hot oven at 400°F (200°C) until nicely browned on top, then garnish with parsley.

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 holds its shape under the sauce.
Milk
Liquid base that, with the flour, thickens into a smooth sauce.
Butter
Fat that carries flavor and helps form a smooth roux with the flour.
Flour
Thickens the milk into a sauce by gelatinizing starch when heated.
Cheese
Melts into the sauce for richness and savory flavor, and browns on top.

The step that matters

Add the milk gradually to the butter and flour. Adding liquid slowly while whisking lets the flour starch disperse evenly, preventing lumps. A smooth base thickens evenly into a silky sauce instead of a grainy one.

Swap the cauliflower

Fit is the average pairing score against milk, butter, flour, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
