Ingredients

Directions

Make the batter

  1. In a bowl, whisk together the eggs, milk, salt, and pepper.

  2. If desired, add flour to create a thick batter.

  3. Dip the slices of stale bread into the batter, ensuring they are well coated.

Fry and serve

  1. Heat a skillet over medium heat and add a little butter.

  2. Fry the coated bread slices in the skillet until golden brown on both sides.

  3. Serve hot, either with pot roasts or as a standalone breakfast dish.

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

What each ingredient does

Eggs
Set during frying to bind the bread and form a tender custard coating.
Milk
Thins the egg mixture so it soaks into the bread and adds moisture.
Stale bread
Absorbs the batter and provides the structure that gets crisp and browned in the pan.
Butter
Adds fat for frying, promoting browning and a rich flavor on the surface.
Flour
Thickens the batter so it coats the bread more heavily.

The step that matters

Fry over medium heat until golden on both sides. Too high a heat browns the outside before the egg in the center sets, leaving the middle wet. Medium heat lets the custard cook through while the surface turns golden.
