Why it works: Olive and tomato are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Assemble
Cover the bottom of an open baking dish with olive oil and scatter grated cheese on top.
Carefully drop the eggs onto the cheese without breaking the yolks.
Season the eggs with coarse sea salt.
Pour cream over the eggs and sprinkle with more grated cheese.
Bake and serve
Bake in the oven for about 15 minutes.
Serve with tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a custard-like texture as they cook, forming the body of the dish.
- Cheese
- Melts and browns on top, adding richness and savory flavor and holding the eggs in place.
- Cream
- Adds moisture and richness, keeping the eggs tender as they bake.
- Olive oil
- Coats the dish to add fat and keep the cheese from sticking.
The step that matters
Dropping the eggs onto the cheese. Eggs must be placed gently so the yolks stay whole. Rough handling breaks the yolks, which spreads yolk through the whites and changes the finished look and texture of the dish.
Swap the tomato
How well each one fits the dish's main ingredients (olive, cheese, egg, cream, sauce):
- Mustardfits about as well
- Tomatothe original
- Capsicumfits about as well
- Spinachfits about as well
Fit is the average pairing score against olive, cheese, egg, cream, sauce. Candidates are from the same food group and used in at least 100 recipes.
