I want to believe that the ingredients listed are real, and that additives aren’t necessary.
Keen watchers would notice that no one in the video are wearing gloves. There’s some pretty good research that shows that gloves in food preparation causes workers to be less clean due to them believing they don’t have to clean / wash as much. I’m willing to believe that also. I’ve worked in some really high end restaurants – nobody wears gloves, ever, and it would be nearly impossible to make fine food doing so.
