Recently, the scene in *The Knockout* where Gao Qiqiang eats dry black coffee powder has left a deep impression on many viewers. Some even dug out instant coffee powder to imitate it, only to end up choking and looking rather狼狈. In reality, there is indeed a group of tough characters who can swallow raw coffee powder without batting an eye—the Italian Mafia. They are fond of a dessert called Lemon Mafia: thin slices of lemon sprinkled with sugar and roasted into caramel, then topped with coarsely ground dark roast coffee powder or simply whole coffee beans, all downed in one bite. The sweet, sour, fragrant, and bitter flavors explode in the mouth instantly, refreshing and alerting. This article explores the origins of this way of eating and includes simple, easy-to-follow steps so you can experience the taste of a "boss" yourself. [more…]

A good cup of coffee should be smooth and mellow, but sometimes we taste a rough, astringent sensation akin to chewing on grape skins. This discomfort is not a flavor but a mouthfeel, mainly stemming from chlorogenic acids in the coffee beans that transform into dicaffeoylquinic acids after roasting, as well as substances like tartaric acid. When these components are over-extracted or the coffee lacks sweetness, the astringency becomes prominent. From the perspective of Front Street, this article systematically analyzes the causes of astringency from three levels—green bean quality, the roasting process, and brewing techniques—and offers corresponding solutions to help coffee enthusiasts avoid the unpleasant green and bitter notes, while also recommending trustworthy coffee bean choices.
