Berry galette

Chill the butter briefly. If using frozen berries, thaw them and let the excess liquid drain.

Mix the flour with sugar and a pinch of salt, cut in part of the cold butter until crumbly, then add the cold water and bring the dough together. Wrap and chill until firm.

Roll the chilled dough out on baking paper into a rough circle and lightly sweeten the center, leaving a border around the edges.

Mix the berries with sugar, corn starch and lemon zest. Spoon the filling onto the dough, fold up the edges, and brush the crust with the remaining butter.

Bake until the galette is golden at the edges and the filling is bubbling.

Let the galette cool before serving, then dust with powdered sugar if desired.
