The trickle-down effect—that notion that high culture eventually makes its way to the masses—is news to none of us, and we've also seen the innovations of the street appropriated by the upper echelons. (The high-low mix is basically something of a cliché at this point.) So it will come as no suprise to you that I've recently been experimenting at home with a phenomenon that originated in the most rarefied kitchens. I've witnessed how even highly creative chefs shamelessly borrow from each other, so I'm not worried that you'll find me pathetically derivative. Take, for instance, that frozen foie gras that David Chang shaves over lychees and pine nuts at Momofuku Ko. Before that, René Redzepi at Noma in Copenhagen was shaving frozen sea urchin over a dish of tiny shrimp and foraged beach mustard. I believe Redzepi was the one who started this whole phenomenon of powders and dusts, serving up reindeer lichen dusted with mushroom powder, and a terrine of baby vegetables covered with a powdered malt "dirt." It's part of Noma's whole ethos of preserving, preserving, preserving—storing up an arsenal of flavors to get through those long Nordic winters. Once you wrap your mind around the idea that you can dehydrate almost anything, then grind or crumble it into a very versatile medium, I think you may jump on this culinary bandwagon (along with the rest of the world).
