Powdered Vinegar


Through a small miracle of science, you can add vinegar flavor to dry foods like popcorn and kale chips, in addition to all the pickles and salads.

A few summers ago, trying desperately to make some green beans less watery and waxy and boring, I tried to make a knockoff version of something I had eaten at Superiority Burger. The dish—advertised maybe as just “salt and vinegar romano beans”—had consisted of some absurdly fresh, vivid pale green beans, cooked ever so lightly until they were buttery and crisp and slightly browned in a few spots, and dusted in what tasted like the powder that coats salt and vinegar chips.

Trying my best to re-create the beans at home, I heated a skillet as hot as I could get it, added some olive oil, and cooked the beans as quickly as possible to keep them fresh-tasting. I sprinkled a little red wine vinegar on at the end and a little handful of salt. Upsettingly, the liquid of the vinegar (and the salt I had sprinkled on top) just kind of slid off the beans, leaving them both soggy and devoid of flavor. Although I like to think of myself as a somewhat experienced home cook, I found myself scratching my head and asking the ether: “How do you get vinegar to stick to a bean?”

I only had to wonder this every day repeatedly for about three years before Brooks Headley’s Superiority Burger Cookbook came out and answered my question. The trick, it turns out, was in doubling down on the vinegar—tossing the beans in a few tablespoons of malt vinegar, but then sprinkling malt vinegar powder on top along with the salt.

Lots of vinegars, it turns out, exist in powder form that you can buy in specialty spice stores or online. You can buy dry versions of everything from plain old white distilled vinegar to a bubblegum pink powdered version of red wine vinegar. This means that in addition to using vinegars to pickle vegetables, deglaze pans, and make vinaigrettes, you can add the flavor to foods that might normally become soggy from the liquid version, like potato chips, popcorn, or spice rubs.

Michael Harlan Turkell, the author of Acid Trip, likes to sprinkled powdered vinegar onto fried chicken—adding a just barely detectable sharpness that cuts through the fat. “Vinegar’s power comes from its acidity, of course, but it’s also about its olfactory ability to release volatile compounds,” he says. “Even in a vinegar, unless it’s bound by enough fat, you’ll often smell it before you taste it. It will make you aspirate. But if you want just the acidic, vinegar powder is a way to focus on the flavor, without all the sensory overload.”

To make a DIY version of the powder, you can boil vinegar with baking soda until the liquid evaporates entirely, but you can also dehydrate the solids from the bottom of a bottle of vinegar, or soak stale bread in vinegar, and let it dry out in a very low-temperature oven before grinding it into a powder in the food processor.

Powdered vinegars that you buy commercially tend to be cut with quite a bit of maltodextrin—a starch that helps keep the powder from clumping up. This makes the flavor pretty mild—less of the smack of vinegar flavor you might get from a salt and vinegar potato chip, and more of a subtle, savory acidity. But when it comes to adding a tinge of flavor to some buttered popcorn, kale chips, crispy smashed potatoes, or a weird snack mix improvised from whatever cereals and nuts you have in your cupboard, then powdered vinegar is your guy.


  • 1 ½ pound fresh beans (such as green or yellow Romanos, wax beans, or green beans), trimmed
  • Grapeseed oil
  • 3 tablespoons malt vinegar
  • 4 tablespoons malt vinegar powder, plus more for dusting
  • 3 tablespoons extra-virgin olive oil
  • Flaky sea salt

This recipe has been excerpted from the Superiority Burger Cookbook. is a bummer. We can all agree on this. They have made a career flattening the little, mighty, important mom-and-pop bookstores out of business. In New York city alone: St. Mark’s Bookshop, Oscar Wilde Bookshop, Murder Ink, for example, all vanished. You can buy anything on Amazon. Compact discs, slacks, fetish hot sauces—you name it, they will sell it to you. We want this warm salad to taste as gripping and succulent as a paper cone of boardwalk fries minus the airborne fryer oil and fingered tubers. The key is powdered malt vinegar, which can be difficult to source. Amazon has it. But order it from a tiny online spice emporium instead; you might not get it in 48 hours, but we will all feel better about this commercial exchange.

  1. Bring a heavily salted pot of water to a boil. Set up an ice bath. Gently drop the beans into the water and let boil for only 20 seconds or so. Immediately plunge them into the ice bath. Once they are cool, drain the beans well and dry with a clean kitchen towel.
  2. In a large skillet, bring a little bit of grapeseed oil to almost smoking over high heat. Drop the beans into the skillet and move them around continuously so they get a nice sear on both sides. Transfer the beans into a large mixing bowl. Add the malt vinegar, malt vinegar powder, olive oil, and a lot of salt and pepper. The seasoning should remind you of boardwalk French fries. Top each serving with a sprinkle of flaky sea salt and a dusting of more malt vinegar powder. Eat with your fingers.
