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 and Tomato Souffle
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.
Make the base
Melt the butter in a saucepan.
Add the flour and gradually stir in the milk.
Bring to a boil over heat, then add the yolks and seasonings.
Fold in the stiffly beaten egg whites.
Assemble
Divide the cauliflower into small sprigs and slice the tomatoes.
In a greased souffle dish, layer some of the mixture, followed by cauliflower and tomato slices, repeating until all ingredients are used.
Finish with a layer of the mixture and sprinkle browned crumbs on top.
Bake and serve
Bake in a hot oven at 400°F (200°C) for 20-30 minutes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and give the souffle its rise and light texture.
- Egg yolks
- Enrich the base and help it set into a custard-like structure as it bakes.
- Flour
- Thickens the milk into a white sauce that holds the souffle mixture together.
- Milk
- Forms the liquid base of the white sauce, adding moisture and softness.
- Cauliflower
- Provides the main vegetable bulk and moisture within the layers.
- Tomatoes
- Add acidity and moisture, contrasting with the mild base.
The step that matters
Fold in the stiffly beaten egg whites. Folding gently keeps the air bubbles in the whites intact. Deflating them makes the souffle rise poorly and turn dense.
Swap the tomato
How well each one fits the dish's main ingredients (flour, cauliflower, butter, milk, pepper, egg):
- Asparagusfits better
- Leekfits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against flour, cauliflower, butter, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
