You always associate getting stoned with eating delicious food. And dining stones are no different. Made of granite and slate set in cherry, alder, or ash wood, they serve as plate warmers or chillers, keeping rations at the appropriate temperature while you eat. How does it work? No wires or batteries necessary, just good old Mother Nature. Simply throw the slab in the oven at 350 degrees or freezer for about fifteen minutes, depending on which job you want it to perform, and it will remain hot or cold for about 45 minutes. If treated right, they’ll last a lifetime. Which is more than you can say for that kind bud. Available online at diningstones.com.
