BUT they are dishwasher safe, like plastic, and require no maintenance to keep them firm and smooth. Our favorite feature? They're thin. We have two that we slide in behind our knife block on the counter. They obviously aren't as weighty and comforting to chop on as a big slab of wood, but they feel substantial and take up much, much less space in a small kitchen.
Epicurean sells pizza peels (the material is heat resistant) and a whole line of boards, from carving boards to a gripper series with silicone feet. The paper used to make them is harvested under the guidelines of the North America Sustainable Forestry Standards, according to the Epicurean website.
The line is available at plenty of big chain stores like Bed, Bath, and Beyond and Williams-Sonoma.
