Chili Pot Woman here. I just read the funniest article which incorporated many reader write-ins about kitchen mishaps. Thought it might be fun to get some of our own going. My worst at the restaurant came when I redesigned a recipe, stating to add raw steak instead of precooking. Unfortunately my cook thought that this included the process of another recipe that used Boston Butt, and chose to cube and add raw pork to a chili recipe. While the flavor ended up fine, there were 2 inches of grease floating at the top.
I know an old trick of placing lettuce leaves on top of a stew to absorb fat. Works great, unless you have the fat of a 10 lb. roast on top. After 6 heads of lettuce, we chose to call it a wash.
