Dark-Chocolate Potato Rosti with Crispy Potatoes

Method

1. Heat the oven and prepare your pan; measure unsalted butter and baking powder precisely.

2. Combine the dry and wet ingredients just until smooth, without overmixing.

3. Fold in mixed berries and transfer the batter to the pan, leveling the top.

4. Bake until set and golden and a tester comes out clean.

5. Cool before slicing so the potato rosti holds its shape.
