Petardo is a type of cocktail that originates from Peru. It is made with Ginger Flavored Liqueur, Pisco, Lime Juice, and Egg white. The Petardo has a fresh and tangy flavor, with the sweetness of the ginger liqueur offset by the acidity of the lime juice. The egg white gives the cocktail a smooth and creamy texture, while the pisco provides a strong alcoholic kick. The history of the Petardo is shrouded in mystery, but it is thought to date back to the early 20th century. It became popular in the 1970s, when Peruvian immigrants began opening bars and restaurants in New York City. Today, the Petardo is a well-known cocktail both in Peru and the United States.
