Summer Berry Cobbler

I will never forget the first time I had this dessert- it was SO amazing. My friend Laurel made it- a Tyler Florence recipe. I have made this many times since, and it is a crowd pleaser. You have to make it at least once a summer.
(Fresh and Easy marks down all their produce/breads/etc. that need to be used right away- so on the morning I made this, I stopped in there and bought all the berries for 50-75 cents a pint.)

1 pint blueberries
1 pint raspberries
1 pint blackberries
1 pint strawberries, hulled and sliced in half
1/2 cup granulated sugar, plus more, for dusting
Pinch cinnamon
2 tablespoons cornstarch
1/2 lemon, juiced
1 recipe scone dough, recipe follows
Melted butter

Preheat oven to 400 degrees F. In a mixing bowl, combine berries with sugar, cinnamon, cornstarch and lemon juice. Stir gently to combine. Spread berry mixture out on a 10-inch tart or gratin dish. Dollop spoonfuls of scone dough evenly over the top of the fruit; leave a border around the edge of the dish for spreading. Drizzle the surface with melted butter and dust with sugar. Set on a cookie sheet and bake for 25 to 35 minutes until the top is golden brown and the fruit juices bubbling. Cool for 15 minutes before serving. Serve with heavy cream, whipped cream or vanilla ice cream.

Scone Dough
2 cups unbleached flour
1 tablespoon baking powder
1 teaspoon salt
1/3 cup sugar
1/4 cup unsalted butter, chilled and cut in chunks
3/4 cup buttermilk or cream
1 egg

In a large bowl, sift together flour, baking powder, salt and sugar; mix thoroughly. Cut in butter using 2 forks or a pastry blender. The butter pieces should be coated with flour and resemble crumbs. In another bowl, mix buttermilk and egg together, and then add to the flour mixture. Mix just to incorporate, do no overwork the dough.
