Dolores beat me to it. Cheez Whiz is not the same thing as the Easy Cheese (Spray Cheese, Cheese in a Can). It is also made by Kraft, no info there on who invented it, perhaps Edwin worked on it as well.
Cheez Whiz is actually pretty good. When I was newly on my own I always kept some Cheez Whiz on hand for making quick Mac and Cheese. It doesn’t taste quite as overprocessed as Velveeta. So thank you, Edwin, may you rest in peace.
Now I am getting a craving for Cheez Whiz Mac and Cheese.
