Gustavo Tosta is the mastermind behind the wildly popular YouTube channels Guga Foods and Sous Vide Everything, and the author of the new cookbook Guga: Breaking the Barbecue Rules. But when Guga isn't cooking up some of the finest steaks known to man, he's snacking on a classic collection of treats from his native Brazil. From the joys of sucking on a packet of doce de leite, to the proper way to drink Yakult using a toothpick, Guga breaks down the dos and don'ts for snacking like a Brazilian YouTube legend.
