Summer Fruit Cobbler with Vanilla-Mascarpone Biscuits
Let the farmers market be your guide when it comes to this cobbler—any mixture of fresh summer stone fruits and berries can be cooked down to make the perfectly sweet-tart, jammy filling. Aim for 2 1/2 pounds (about 10 cups) of fruit total, using any combination of the following: blackberries, blueberries, or raspberries; Bing or Rainier cherries (stem and pit them first); stone fruit (pitted and sliced into 3/4-inch wedges; you can leave the skin on plums or apricots but should peel peaches and nectarines). Tender vanilla-mascarpone biscuits have a shortcake-like texture and a delightfully crunchy top from the turbinado sugar. They're also highly customizable: You can swap the mascarpone in the biscuit topping for crème fraîche or sour cream if that's what you have, and trade the semolina for fine cornmeal for a more crumbly texture.
