1. В В Adjust an oven rack to the middle position and preheat the oven to 400°F. 2. В В Gently toss the berries with the palm sugar, vanilla, and salt, then spread into a 1½-quart casserole or gratin dish. 3. В В Pulse the bread, palm sugar, coconut oil, and cinnamon together in a food processor until the mixture resembles coarse crumbs (about 10 pulses).

Sprinkle the crumbs evenly over the fruit. 4. В В Bake the gratin until the crumbs are a deep golden brown and the fruit is hot (15 to 20 minutes), rotating the dish halfway through baking.

Let cool on a wire rack for 5 minutes before serving.
