Chinese vendors use cooking oil dredged from gutters
Had you ever worried about the quality of some Asian street food, then this won’t help to settle your mind. Although illegal, the practice detailed in the video is thought to be widespread in China – street food vendors dredge gutters for congealed cooking oil used by a previous vendor, and ‘recycle’ it for use on their own stalls. It’s a lucrative business for ‘gutter oil vendors’, and a cheap means of getting that essential ingredient for street food.
