• 8 fresh peaches – peeled, pitted and sliced into thin wedges
• ¼ cup white sugar
• ¼ cup brown sugar
• ¼ teaspoon ground cinnamon
• ⅛ teaspoon ground nutmeg
• 1 teaspoon fresh lemon juice
• 2 teaspoons cornstarch
• 1 cup all-purpose flour
• ¼ cup white sugar
• ¼ cup brown sugar
• 1 teaspoon baking powder
• ½ teaspoon salt
• 6 tablespoons unsalted butter, chilled and cut into small pieces
• ¼ cup boiling water
• 3 tablespoons white sugar
• 1 teaspoon ground cinnamon

Preheat the oven to 425 degrees F (220 degrees C). Combine peaches, 1/4 cup white sugar, 1/4 cup brown sugar, 1/4 teaspoon cinnamon, nutmeg, lemon juice, and cornstarch in a large bowl; toss to coat evenly, and pour into a 2-quart baking dish. Bake in preheated oven for 10 minutes. Meanwhile, combine flour, 1/4 cup white sugar, 1/4 cup brown sugar, baking powder, and salt in a large bowl. 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. Mix 3 tablespoons white sugar and 1 teaspoon cinnamon together in a small bowl; sprinkle over entire cobbler. Bake in the preheated oven until topping is golden, about 30 minutes.
