If you’re looking for a new way to prepare a meal and impress dinner guests, check out SteakStones ($136). After heating the lava stone in the oven, it stays hot for 20-30 minutes — plenty of time to sear and cook a steak, seafood, or lamb however you like it. It rests neatly in its cradle, warming any food below, and providing a serving station for your meal. Get several steak stones and allow your guests to prepare their own meat, or get the sharing platter and cook for two.
