Trundle through as many fancy restaurant kitchens as I have and you'll start recognizing specialized tools, big and small: little offset spatulas, slablike flat-top griddles, high-powered Vitamix blenders, spoonulas. For years now, many of those kitchens also used something that looks like a cross between a black squirt gun and a battery-powered hookah.
This thing, the PolyScience Smoking Gun, uses a tiny fan to draw a flame across a teaspoon of wood chips or other combustibles to produce a steady stream of smoke, which it expels through a long tube. You can do some pretty cool things with it: I've seen chefs present food under a clear glass cloche full of smoke, lifting it tableside to reveal a dish; bartenders will smoke a glass, the booze, or an entire cocktail to impart varying degrees of smokiness. When I worked on The Willows Inn’s cookbook, Sea and Smoke, chef Blaine Wetzel would cold-smoke mussels in a smoker for four hours, sear them on the flat top to caramelize them, tuck them back in their shells, pop them in a tiny cedar box, pipe alder smoke into the box, and immediately walk it out into the dining room, where diners opened the box, sending a puff of smoke billowing toward the ceiling.
Despite its ability to turn a dish or a drink into a showstopper, the original Smoking Gun, like that plastic squirt gun, feels a bit chintzy. It's also poorly balanced: Even in its stand, a tug on the tube can cause the whole thing to fall over and make a literal hot mess.
