Roast Apples

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

Preheat the oven to 350°F (175°C).
Scoop out the center of the apples, removing all the seeds.
Fill each apple with butter, cloves, brown sugar, and lemon peel.

Roast and serve

Place the apples in the oven and roast until tender.
Serve the roasted apples on croutons of bread fried in butter.

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

What each ingredient does

Apples: Provide the main body that softens and turns tender when roasted.
Butter: Adds richness and moisture, carrying flavor as it melts into the apple.
Brown sugar: Adds sweetness and helps the apple surfaces brown as they roast.
Cloves: Contribute warm, aromatic spice flavor to the filling.
Lemon peel: Adds bright aroma that balances the sweetness of the sugar.
