Jambu, Szechuan button

What’s the buzz? Dallas bartenders use mouth-tingling Brazilian bud to jazz up cocktails

In Deep Ellum, Hide’s Green Tara may drink crisp and refreshing, but a little bit of buzz button changes everything.

At Hide in Deep Ellum, the Green Tara is a lovely, lemonade-hued cocktail, dressed with dehydrated citrus and an eye-catching yellow bud that looks like a little knit gumdrop.

The drink – a vodka-based number flaunting pear, jasmine green tea, vanilla bean, lime and lemon – is tart, crisp and refreshing, with soft, herbal notes. But take a crunch of that fuzzy little bud and within seconds, your mouth lights up like a state fair midway.

And, notes bar director Scott Jenkins, “it totally changes the dynamics of the drink.”

The Brazilian jambu goes by many names, but here in the U.S., it’s most commonly known as the buzz button. The flowering part of an herb known as Acmella oleracea, it’s less known for its looks than its effects on the palate, caused by the release of a natural chemical compound called spilanthol.

“It’s like putting a nine-volt battery on your tongue,” says bartender Spencer Shelton of Ruins in Deep Ellum, which uses buzz buttons – referred to on the menu as “Brazilian bud” – in Armando Guillen’s appropriately named Cojones! My Tongue! “It’s kind of Pop-Rock-y.”

At Ruins in Deep Ellum, Armando Guillen’s Cojones! My Tongue! features rum, soursop syrup and lime, but it’s the buzz button that gives the drink its exclamatory name.

The bud’s initial taste is grassy, almost straw-like, before the electricity kicks in – a hint of sour as it prompts salivation, then a prolonged carbonated tingling on the tip of your tongue. The sensation is almost numbing. “There’s a slight analgesic quality to it,” Hide’s Jenkins says.

And it’s one more way to perk up the cocktail experience. The first time I ever encountered one was in 2012 in Las Vegas, where a buzz button graced an Asian-influenced Margarita variation at The Chandelier Bar at The Cosmopolitan. Guests were urged to drink half the cocktail before eating the bud to experience the drink’s altered state: The tingle on the tongue lent a jolt of effervescence.

At Hide, the Green Tara starts with a burst of green tea and citrus, followed by the soft sweetness of pear. A bite of buzz button bumps up the drink’s floral components, sweetens the citrus and creates a bubbly sensation as you drink.

I also saved a bite of buzz button to try with Hide’s tequila-based Yellow Belly, which features yellow bell pepper, Yellow Chartreuse, lemongrass and coriander; it beautifully boosted the pepper’s sweet, vegetal brightness.

In a way, the buzz button experience is a micro version of the flavor tripping parties that were trendy a decade ago, where people gathered to chomp on miracle fruit berries and then marvel at how Tabasco suddenly tasted like doughnut glaze or cheap tequila like, well, really awesome tequila.

Bartenders say jambu’s sensation works best with citrus and clear spirits like gin, vodka and tequila, “really any kind of patio drink,” Ruins’ Shelton says. “It’s mouthwatering and refreshing. It just begs you to drink more.”

Several years ago, when Shelton worked at Bolsa, near Oak Cliff’s Bishop Arts District, he and then-bar manager Kyle Hilla were researching herbs when they came across jambu.

Curious, they turned to Cynthia Mulcahy of Mulcahy Farms, who’s grown herbs and edible flowers for Bolsa for years. “She was pretty much our personal botanist,” Shelton says.

As it turned out, Mulcahy was already familiar with the plant, having traveled to Brazil annually for 15 years. “It’s something you find in Rio de Janeiro and other places,” she says. “They have herb farms in the hills that ring the city. It’s the most beautiful thing you’ve ever seen. It’s like the Italian countryside.”

Mulcahy started growing buzz buttons for Bolsa, where Shelton and Hill – now beverage director for the Statler Hotel – used them on drinks and randomly handed them out to unsuspecting patrons to see their reaction.

“Sometimes people freak out,” Shelton says. “Everything from curse words to just saying, ‘Ow!’ It’s one of a kind, and you don’t expect it. It’s just fun, that’s my favorite thing about it.”
