Yeh, it's an open rack (just the 4 corner posts with shelves and bracing) designed for this stuff,. There's no back or sides on it and the shelves are made of 1 1/2 wood slats with 1/2 spaces in between for air flow under and above. I made it tall and divided up the shelf height so there would be room for different (larger) toaster over & microwave when it came time to replace them.
That liner looks interesting. Will definitely work better than my foil fix, since you can just lift it out to clean it. I saw that Beville makes a 13" pizza stone for almost $50. I'll shop around (lots of dubious quality out there), but will definitely get a stone. It will be nice to make individual pizza crusts and freeze them, and not have to fire up the big oven.
I was looking at the model that's also an air fryer. I've wanted (but certainly not needed) an air fryer but lack the room for it. This would be both-in-one. Most people who have an air fryer really like it. Gotta think about it.
Thanks for all the advice! (You, too, Pinky!)
Keep it coming!!!
