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 ↓

Eggs in Tomatoes

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.

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. Cut off the top of each tomato and scoop out some of the flesh.

  3. Sprinkle a little salt and pepper inside each tomato.

  4. Crack one egg into the cavity of each tomato.

Bake and serve

  1. Bake in the oven until the egg is cooked to your liking.

  2. Serve the tomatoes on rounds of toast.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Egg and pepper barely smell alike, yet cooks put them together in 50,580 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Hold the eggs in shallow cups and add moisture and acidity as they soften.
Eggs
Set as they bake, forming a tender, cooked filling inside each tomato.
Toast
Provides a crisp base that soaks up juices and supports the tomatoes.

The step that matters

Baking until the egg is cooked to your liking. Egg white sets at lower temperatures than the yolk, so checking early helps avoid a runny white or an overcooked, rubbery yolk. Tomato juices also release as they heat, so watch the egg rather than the clock.

Swap the tomato

How well each one fits the dish's main ingredients (egg, pepper):

  1. Capsicumfits better
  2. Spinachfits better
  3. Asparagusfits better
  4. Tomatothe original

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