6 large peaches, cut into thin slices
1/4 cup sugar
1 tablespoon fresh lemon juice
1 teaspoon cornstarch
For biscuit topping
1 cup all-purpose flour
1/2 cup sugar
1 teaspoon baking powder
1/2 teaspoon salt
3/4 stick cold unsalted butter, cut into small pieces
1/4 cup boiling water
Preheat oven to 425°F. Toss peaches with sugar, lemon juice, and cornstarch in a 2-qt. nonreactive baking dish and bake in middle of oven for 10 minutes.
Make the topping while the peaches bake: Stir together flour, sugar, baking powder, and salt. Blend in butter with your fingertips or a pastry blender until mixture resembles coarse meal. Stir in water until just combined.
Remove peaches from oven and drop spoonfuls of topping over them. Bake in middle of oven until topping is golden, about 25 minutes. (Topping will spread as it bakes.)
*In the future, I might double the topping recipe, as it comes out a bit thin. Not too thin, but if you’re looking for something more substantial, I would recommend doubling it.
Serve with vanilla ice cream, homemade if you have time / are overly ambitious.
