Why it works: Tomato and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boiled Cauliflower with Tomato Sauce
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 the cauliflower
Boil the cauliflower until tender, then chop it coarsely.
Press the chopped cauliflower hard in a bowl or mold to keep its shape.
Place the molded cauliflower on a heatproof dish.
Make the sauce
In a saucepan, cook the butter and flour together.
Pour in the strained tomato juice that has been stewed with half an onion.
Stir until smooth, then thicken with cracker dust and season with salt, sugar, and paprika.
Bake and serve
Pour the sauce over the molded cauliflower and bake in a 400°F (200°C) oven for about 10 minutes.
Serve in the dish it was cooked in.

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 when pressed into a mold.
- Butter and flour
- Cooked together they form a roux that thickens the tomato sauce.
- Strained tomato juice
- Forms the liquid base of the sauce, providing its moisture and tangy flavor.
- Cracker dust
- Further thickens the sauce, giving it body as it is stirred.
- Onion
- Stewed in the tomato juice to add savory aroma to the sauce.
The step that matters
Stir the sauce until smooth before thickening. Adding liquid to the roux too quickly or unevenly can leave lumps. Stirring as the liquid goes in keeps the flour evenly dispersed so the sauce thickens smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (cauliflower, sauce, butter, flour, onion, sugar):
- Mustardfits better
- Shallotfits better
- Turnipfits better
- Tomatothe original
Fit is the average pairing score against cauliflower, sauce, butter, flour, onion, sugar. Candidates are from the same food group and used in at least 100 recipes.
