On tonight's Top Chef finale (no spoilers here, don't worry), Richard bragged that he was using liquid nitrogen to make ice cream, and that "only a dozen top chefs in the country" do that sort of thing.
Top chefs, pffft. Even I've made liquid nitrogen ice cream on multiple occasions. In fact, other than procuring liquid nitrogen, it's one of the easiest desserts out there. Clearly Richard should have noted that "a dozen top chefs and thousands of physics geeks" use liquid nitrogen in their cooking.
