American Apple Charlotte

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 350°F (175°C).
Peel and slice the apples.
Grease a baking dish with butter.

Layer and bake

Layer half of the bread slices at the bottom of the dish.
Spread half of the apples over the bread.
Sprinkle with sugar and cinnamon or nutmeg.
Repeat the layers with the remaining bread and apples.
Dot the top with butter.
Bake until the apples are tender and the bread is browned, about 30-40 minutes.

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

What each ingredient does

Bread: Forms the structure of the charlotte and browns on top as it bakes.
Apples: Provide the fruit filling, which softens as it bakes into a tender layer.
Butter: Adds richness and helps the top brown while coating the dish and bread.
Sugar: Sweetens the apples and helps the top caramelize and brown.
