1. Preparation
2. Arrange racks in top and middle of oven; preheat to 375°F. If bread is not a day old or still feels moist, arrange slices in a single layer on a baking sheet and bake, flipping once, until dry to the touch but not toasted, 5–10 minutes.
3. Using a 2" ring or cookie cutter or sharp paring knife, cut a hole in the center of 4 bread slices. Trim bread to fit in 2 even layers in a half-hotel pan, with the whole slices on the bottom and the slices with holes on the top, forming 4 sandwiches. Once fitted, remove the bread from the dish.
4. Meanwhile, melt butter in a medium pot over medium heat. Add flour and cook, whisking constantly, until butter foams then subsides (make sure it doesn't brown), and mixture is light gold and thickened, about 3 minutes.
