The well-known tea beverage brand Yihotang has been exposed by media undercover investigations at multiple stores in Zhengzhou for serious food safety issues: ingredients that should have been discarded after closing were used again the next day, expired materials had their labels swapped to extend their shelf life, moldy strawberries were washed and used as usual, flying insects that fell into toppings were fished out and still used in products, and even prepared drinks in which bugs were found were resealed and continued to be sold. Even more shockingly, the staff were indifferent to this, claiming that "as long as it doesn't kill people, it's fine." After the incident was exposed, Yihotang issued an apology statement, and the stores involved were closed for rectification. Lawyers pointed out that the relevant actions have violated multiple provisions of the Food Safety Law. Netizens reacted differently, with some saying that chaos in franchise stores is common, while others called on the brand to effectively fulfill its regulatory responsibilities. [more…]

Bamboo tube milk tea has quickly become popular thanks to its unique bamboo tube container, often selling for over thirty yuan, making it a new-generation internet-famous drink. However, recently some consumers discovered that beneath the sticker on the surface of the bamboo tube there was another label, raising doubts that the bamboo tubes were being recycled and reused.

When most people think of a combination of milk and espresso, the first things that come to mind are classic milk coffees with milk foam, such as lattes and cappuccinos. But the same ingredients, processed with a different method, can take on a completely different appearance and texture. This article introduces a technique called "milk washing"—using the principle that casein coagulates when milk meets acid to remove the fat and protein particles from milk, leaving behind a transparent whey liquid. This time, Front Street Coffee's approach differs from the usual one: during the clarification process, espresso is added directly, so that the entire drink is clarified together, resulting in a "special latte" that looks similar to pour-over coffee but has rich, layered flavors. The article will explain in detail the required materials, recipe ratios, and step-by-step instructions, making it a useful reference for enthusiasts who want to try making specialty coffee at home.
