Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomatoes for Breakfast
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 tomatoes
Preheat the oven to 400°F (200°C).
Cut the tomatoes in half and place them in a pan, skin side down.
Add a piece of butter on each tomato and sprinkle with salt and pepper.
Bake and make the sauce
Bake until the tomatoes are tender.
Remove the tomatoes with a spatula onto a hot serving dish.
In the same pan, add the cream to the juice and bring to a boil.
Thicken the cream mixture with flour and pour it over the tomatoes.
Serve with hot toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Soften during baking and release juice that mixes with the cream to form the sauce.
- Butter
- Adds richness and fat that helps the tomatoes brown and carries flavour across the surface.
- Cream
- Forms the rich body of the sauce, adding fat and a smooth, creamy texture.
- Flour
- Thickens the boiled cream and juice mixture so it clings to the tomatoes.
The step that matters
Thicken the cream mixture with flour. Flour must be cooked in the hot liquid to swell and thicken the sauce. Adding it to cold or unboiled cream can leave lumps or a starchy taste, so bring the cream to a boil first and stir steadily.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, cream, flour):
- Spinachfits better
- Leekfits better
- Potatofits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
