I thought they might turn hard as a rock overnight if I didn't freeze them, or at least hard before I could eat all of them. when you buy Super Pretzels, they are frozen and you nuke them for 30 seconds and they come out fresh, so I just did the same thing. I actually liked them better after a night of freezing for some reason, the spicy cheese sauce might helped with that though. and I used the big Super Pretzel Salt. I plan on to continue making them so as to keep stock on hand in the freezer.
With just the butter and salt fresh out of the oven, it reminded me of breakfast biscuits, but after a night of freezing and the cheese sauce it was all pretzel.
