Columbus Eggs

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Cut off the tops of the green peppers and remove all seeds.

  2. Stand the peppers upright in a sauté pan.

  3. Break an egg into each pepper.

Bake and serve

  1. Bake in a 350°F (175°C) oven for 8 to 10 minutes.

  2. Serve the peppers on toasts and pour a little tomato sauce around.

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

What each ingredient does

Eggs
Set into a soft, custard-like filling that cooks inside the pepper cups.
Green peppers
Act as edible cups that hold the egg and keep it contained while baking.
Tomato sauce
Adds moisture and acidity to balance the rich egg.

The step that matters

Baking the eggs. Eggs set quickly once heated, so the 8 to 10 minute bake can overcook them into a rubbery texture. Checking early keeps the yolks soft while the whites firm.

Swap the tomato

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

  1. Capsicumfits better
  2. Spinachfits better
  3. Asparagusfits about as well
  4. Tomatothe original

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