In mid-October, the OU officially rejected certification of Impossible Pork, causing a flurry of contention from kosher-keeping consumers. What does it mean for rabbis to declare a product of 100% kosher ingredients treif based on name and taste alone?

David’s opinion piece on the subject can be found here.
