Eggs in Tomato

Ingredients

Directions

Prepare

  1. Chop the onion into small pieces and place it with the tomato in a frying pan.

Make the sauce

  1. Stew slowly for 10 minutes, then add the salt and pepper.

Cook and serve

  1. Break the eggs and carefully slip them on top of the tomato, avoiding breaking the yolks.

  2. Return the pan to the heat and cook slowly until the egg whites are set.

  3. Prick the yolks to let them mingle with the tomato and whites.

  4. Serve immediately on buttered toast.

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

What each ingredient does

Eggs
Egg whites set into a firm structure while the yolks stay soft and mix into the sauce.
Tomato
Forms the moist, acidic base that the eggs cook in.
Onion
Adds savory flavor to the stewed tomato base.

The step that matters

Slipping the eggs onto the tomato. Eggs cooked gently over low heat set evenly. Breaking the yolks early or cooking too fast makes the whites rubbery and the dish watery.

Swap the onion

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

  1. Capsicumfits better
  2. Spinachfits better
  3. Eggplantfits better
  4. Onionthe original

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