How to Make It
Preheat the oven to 350°. In a food processor, pulse the flour, cornmeal, 3 tablespoons of the granulated sugar, the baking powder, cinnamon and salt to combine. Add the butter and pulse until the mixture resembles coarse meal. Add the 2/3 cup heavy cream and pulse just until a smooth dough forms. On a lightly floured surface, pat the dough into a ball. Flatten slightly, then roll out the dough to a 1/2-inch thickness. Using a floured 1 1/2-inch round biscuit cutter, stamp out 32 rounds; pat the scraps together and reroll if necessary.
In a medium bowl, toss the berries with the honey, orange juice, lemon zest, potato starch and the remaining 2 tablespoons of granulated sugar. Pour the berries into a 2-quart baking dish. Arrange the biscuit rounds over the fruit in rows so they touch but do not overlap. Brush the rounds with the remaining 1 tablespoon of cream and sprinkle with the turbinado sugar. Bake for about 50 minutes, or until the fruit juices are bubbling and thickened and the biscuits are golden brown. Let cool slightly then serve with ice cream.
Turbinado sugar is a coarse, brown-colored raw sugar that's available at specialty food stores and supermarkets.
