A Hearty Nomad

"The taste is a bit tangy, probably because of the kind of pepper they use, however, the highlight of the dish is the tingling sensation the jambú leaves on your tongue and lips, it’s almost numbing. In short, I would describe it as icky but EXTREMELY DELICIOUS. A must try."

"Tacaca, an unusual soup made with traditional amazonian ingredients; Tucupi, a yellow toxic (when raw) liquid extracted from the manioc root, Jambu leaves, (known as the toothache plant for its slightly anaesthetic properties), shrimp and tapioca gum. The result? A sour version of Tom Yum Goong that makes your lips go numb. Definitely what you would call interesting."

"Tacacá is a strange soup which mixes gloopy manioc gum, large shrimps, a rich, tangy broth called tucupí and a leaf called jambu which has quite a strong anaesthetic effect. Within seconds of tasting the soup your tongue starts to tingle and your lips go numb. It's a strange, interesting sensation and one I'd recommend at least trying (though not everyone loves it)."

"Non-locals may find the signature dish on the menu–a tangy soup with an ingredient that numbs the mouth–a little intimidating, but it’s a magnificently unique experience if you’re brave enough to try it."
