8 slices white sandwich bread – day-old preferred
Instructions
Preheat the oven to 300°F (150°C) with a rack in the middle.
Trim the crusts from the white sandwich bread slices, then cut each slice diagonally into 2 triangles.
Arrange the bread triangles in a single layer on a baking sheet.
Bake until the surfaces are dry and just pale golden, 8–10 minutes, turning once halfway through.
Transfer the lightly toasted triangles to a cutting board. Using a sharp serrated knife, carefully split each triangle horizontally to make 2 thin wafers.
Return the split pieces to the baking sheet, untoasted inner sides facing up.
Bake again until crisp and evenly golden, 8–12 minutes; rotate the pan once for even color. The toasts are done when dry throughout and the edges curl slightly.
Cool completely on a wire rack until snappy, about 5 minutes. Serve once cooled or store airtight when fully cool.
