Professor Mark Post, who is part of the faculty at Maastricht University in the Netherlands, has been asking that question for almost a decade now. Two years ago, Post’s team of researchers presented their first major discovery in the form of a five-ounce hamburger patty, which was created in a lab, but still was remarkably similar to ones sold on supermarket shelves. The reception was promising: The media was abuzz, and the BBC made several food critics try it, one of whom conceded “this is meat to me, it’s not falling apart.”
