Makes one 9 × 5-inch/23 × 12.7 cm loaf
I FIRMLY BELIEVE THAT ALMOST ANY BREAD CAN BE IMPROVED UPON BY TOASTING it and slicking it with salted butter. This bread, basically a giant English muffin with enough nooks and crannies to make Mr. Thomas blush, is intended to be baked specifically for the purpose of toasting it the next day. And happily, as yeasted bread recipes go, it doesn’t get much more low-effort than this. In my travels across the region, I most often saw this bread baked in an old-fashioned German Rehrucken (crimp loaf pan), which I love the look of; it’s often found as a hinged, cylindrical pan with pretty ridges all around its circumference, and flat ends so that every last slice is identical in shape and size. I managed to snag one of these pans at a thrift store, but a regular loaf pan works just as well.
Nonstick cooking spray for pan
3 tablespoons/30 g yellow cornmeal, divided
2¼ teaspoons instant yeast
⅓ cup/75 g warm water (110° to 115°F/43° to 46°C)
1 tablespoon granulated sugar, divided
3 cups/384 g unbleached all-purpose flour, spooned and leveled
1½ teaspoons fine sea salt
¼ teaspoon baking soda
1 cup/225 g well-shaken buttermilk, at room temperature*
2 tablespoons plus 1 teaspoon/32 g vegetable oil
1 tablespoon unsalted butter, melted
Lightly spray a 9 × 5-inch/23 × 12.7 cm metal loaf pan with nonstick cooking spray, wiping away any excess that pools in the edges of the pan. Dust the pan all over with about 2 tablespoons of the cornmeal, tapping out the excess.
In a small bowl, whisk together the yeast, warm water, and 1 teaspoon of the sugar. Let rest for a couple of minutes.
In the bowl of an electric mixer fitted with the paddle attachment, whisk together the flour, the remaining 2 teaspoons of sugar, salt, and baking soda. On low speed, stir in the buttermilk, oil, and finally the yeast mixture. Increase the speed to high and mix for 1 minute, stopping halfway through to scrape down the bowl. The dough will be soft and sticky. Scrape the dough out into the prepared pan. Oil your hands lightly and pat the dough gently and evenly into the pan. Sprinkle the top with the remaining tablespoon of cornmeal. Cover with plastic wrap and let rise until doubled and the dough comes about 1 inch from the top of the pan, about 1 hour.
During the rise, position a rack to the center of the oven and preheat it to 400°F/200°C. Bake the bread until golden and risen, with a hollow sound when tapped in the center, 22 to 25 minutes (the internal temperature should register at least 190°F/88°C on an instant-read thermometer). Turn out the bread onto a wire rack. Brush lightly all over with the melted butter. Let cool completely before slicing.
*It’s very important that the buttermilk not be fridge-cold, so that the dough can rise well.
