Hello everyone! Something came to my attention the other day at work when I was blanching/shocking some green veggies. One of my sous chefs tasted my asparagus after I had blanched and shocked it and asked if I salted my shocking water. I have never been told to do so, neither in culinary school nor in real life applications. I tried to look up information about this practice in Harold McGee's On Food and Cooking, but he did not have info on it either. Is it necessary? Any help is appreciated!
