I contacted the company that makes Fri Chick. They told me that the recipe changed a year ago and if the can was exposed to heat the sauce would separate and congeal. It was totally safe to eat. EWWWWW!!!!!!! But they were concerned that the top 2 inches of the can was empty so would send me a coupon to replace the can. I AM NOT eating that. YUCK!
However I imagine that when we make Fri Chick gravy out of the sauce we will not need to add a thickner anymore. Just heat it up. I am not sure if that is a good thing or a bad thing
