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 ↓

Another Breakfast Dish

Oven, in the book's wordsA very hot oven

Ingredients

Directions

The book says “a very hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.

Prepare the tomatoes

  1. Cut a slice from the top of each tomato.

  2. Remove enough pulp to fit a bit of butter and a raw egg inside each tomato.

  3. Wrap a strip of bacon around each tomato and secure with a toothpick.

Bake and serve

  1. Sprinkle salt and pepper on top.

  2. Bake in a very hot oven (400°F / 200°C) until the eggs are set, about 5 to 8 minutes.

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

What each ingredient does

Eggs
Set to a firm, tender filling inside the tomato as they cook.
Tomatoes
Hold the egg and release moisture and acidity that flavour the filling as they bake.
Bacon
Adds salty, smoky fat that browns and seasons the outside of the tomato.
Butter
Adds richness and fat that carries flavour and keeps the egg tender.

The step that matters

Bake until the eggs are just set. Egg proteins set quickly with heat, so overbaking turns the yolk chalky and the white rubbery. Checking early at the short end of the time keeps the yolk soft if you want it runny.

Swap the tomato

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

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

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