Mrs. Anderson's Baking Bread Warming Tile keeps bread hot throughout a meal. The high-fired terracotta clay maintains heat for approximately 45 minutes, depending on ambient temperatures. Simply heat the tile in a preheated toaster or oven (350-degrees Fahrenheit) for 15 minutes. Use tongs or oven mitts to place the heated tile in the bottom of a cloth-lined bread basket or dish. Set warmed bread on top of the tile and enclose them with the cloth. It's ideal for serving warmed crusty artisan breads, dinner rolls, biscuits, croissants, tortillas, muffins, and other types of baked goods. Made from high-fired terracotta clay, Mrs. Anderson's Baking Bread Warming Tile is reusable, food safe, and heat safe (to 1,112-degrees Fahrenheit).
