No-Knead Focaccia with Peaches & Prosciutto

Whisk water, honey, salt and yeast in a large bowl. Stir in bread flour and whole-wheat flour, scraping down the sides and mixing until the dough is combined. It should be slightly sticky but come together in a uniform ball. (If the dough is too sticky to form a ball, add 1 to 2 tablespoons bread flour.) Lightly grease a large bowl, place the dough in it and turn to coat. Cover with plastic wrap.

Let the dough rise at room temperature until doubled in size, 12 to 18 hours.

Spread 1 tablespoon oil on the bottom and up the sides of a 9-by-13-inch baking pan. Transfer the dough to the pan and, with oiled hands, gently stretch until it fills the pan and is evenly thick. (If the dough springs back or is resistant, let it rest for 10 minutes, then proceed.) Brush the dough with the remaining 1 tablespoon oil. Using your fingertips, make deep indentations all over the top.

Scatter prosciutto, peach slices and goat cheese evenly over the dough. Cover loosely with plastic wrap and let rise at room temperature until the dough is puffed and fills the pan, about 45 minutes.

Position racks in upper and lower thirds of oven; preheat to 475 degrees F.

Bake the focaccia on the lower rack until the bottom is golden, about 15 minutes. Transfer to the top rack and bake until golden-brown and the bottom sounds hollow when tapped, about 5 minutes more. Let cool in the pan on a wire rack for 10 minutes before slicing. (The focaccia is best enjoyed the day it's baked.)
