1) Preheat the oven to 350°F. Lightly grease a 9" round pan.
2) To make the filling: Combine all the filling ingredients, and spoon the peaches into the prepared pan.
3) To make the topping: Whisk or sift together the flour, salt, baking powder, and sugar.
4) Stir in enough heavy cream to moisten the dough thoroughly. You'll probably use about 1 cup in the summer, 1 1/4 cups in the winter, and 1 cup + 2 tablespoons at the turn of the seasons. You want to be able to gather the dough together, squeeze it, and have it hang together, without dry bits falling off.
5) Pat the dough into a lightly greased 9" round pan. Use a 2" round biscuit cutter to cut as many biscuits as you can, leaving them in the pan. Turn the pan over onto a lightly greased or lightly floured surface, rapping it a few times to make the dough fall out. Lift off the pan, pick up the cut biscuits, and space them atop the peach filling. You'll have leftover biscuit dough; shape it into additional biscuits to bake separately, if desired.
6) Brush the biscuits with milk or butter, and sprinkle with coarse white sparkling sugar, if desired.
7) Bake the cobbler for 45 to 50 minutes, until the filling is bubbly and the biscuits are golden brown.
8) Remove the cobbler from the oven, and let it rest at room temperature for about 20 to 30 minutes before serving; this allows the filling to set somewhat. Don't worry, it'll still be warm when you serve it.
9) Scoop the cobbler into serving dishes, including a biscuit with each serving. Top with vanilla ice cream, if desired.
Yield: about 12 servings.
