Eat Dirt! No, Really, Eat Dirt.: We like a clean kitchen here at the Test Kitchen, but apparently not everyone feels the same way. The restaurant Ne Quittez Pas in Tokyo has come up with a menu featuring dirt in every dish. There was a potato starch and dirt soup, a salad with dirt dressing, dirt ice cream, and dirt gratin. The company Protoleaf came up with the “dirt,” a mixture of coffee grounds and palm fiber which had been thrown in the trash, from which the company has created an eco-friendly compost that is also apparently edible, and, judging from the reviewer’s dining experience, cleaner in taste than one would expect.
