I was on travel, visiting my friend and promised to make my one of my famous pizzas.
The oven was obviously from the late 50's or so and looked as though it had never been cleaned.
I spent a day scrubbing it to get it to "acceptable". But residue still remained.
The oven smoked like crazy when I cranked it up,
the pizza was infused with a such a wonderful smokey flavor, that we really enjoyed.
Not willing to let my oven go, just for smoky flavor LOL!
