Velveeta and Cheez Whiz are sort of the same like, Coke and Pepsi are sort of the same. There are fans of Coke that won't touch a Pepsi and vice versa.
I prefer Cheez Whiz because it starts out at a better consistancy, melts better and stays gooey, while I find Velveeta to congeal much faster unless you dumb it down with some other dairy product. But to each their own!
Now, how's that tummy doing?
You've put a lot of thought into this haven't you?
