A hotpot restaurant in Sichuan, China, has found itself in hot waters after authorities uncovered its shocking practice of using "saliva oil." The term refers to recycled chili oil soup left by customers, which was then blended with new oil and served to the restaurant's next batch of customers.
A diner gave a tip-off to government authorities, prompting an investigation. The authorities then busted the restaurant for recycling leftover "old oil" and adding it to its hotpot soup base, reported the South China Morning Post.
