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 form the custard coating that holds the bread together.
- Milk
- Adds moisture to the egg mixture, keeping the bread soft inside after soaking.
- Bread
- Soaks up the egg mixture and browns in the butter to form the toast.
- Butter
- Conducts heat to the bread surface and adds fat for browning and flavor.
- Sugar
- Adds sweetness and helps the exterior caramelize slightly when sprinkled on the hot toast.
The step that matters
Fry the coated bread slices in the hot butter until golden brown on both sides.. The butter must be hot enough to brown the egg-coated surface quickly. If the heat is too low, the bread absorbs excess liquid and turns soggy before the egg sets and browns.
