A simple search for the hashtag #springonionlatte on TikTok or Instagram reveals photos and videos of latte cups topped with scallions.
According to Harper's Bazaar India, this unconventional drink became a sensation in China in May, with many describing it as one of the most surprising combinations ever attempted.
The preparation of this beverage involves using only the green parts of fresh spring onions, which are chopped and set aside. The base of the drink is an iced latte, made with ice, a choice of milk, and a shot of espresso. This mixture is then poured over a handful of spring onions. Once the latte is prepared, it is generously garnished with the chopped onions.
Reactions to green onion coffee have been mixed.
"I love green onions, but not in my coffee," one TikTok user wrote.
"I never thought that one day I would have to order coffee without onions," a diner shared.
However, some appreciate the complexity it brings to the palate. "It definitely has a spicy aftertaste the more I get into it," a barista from Ben Ledi Coffee in Scotland said. "I don't hate it," he added, as reported by VegNews.
Others find the drink peculiar and question whether the taste is truly as delightful as rumored.
According to Must Share News, green onion coffee is part of China's "dark cuisine," a food trend that challenges conventional notions of what is considered appealing.
Other coffee-related dark cuisine includes oyster coffee, beef broth latte, soy sauce latte, or century eggs added to coffee.
