I was thinking of these also, but we use a stand with a candle under it to keep hot, there may be some burning issues, i think they are plastic, would they work over a candle ???
Never really thought aluminum trays were that bad looking… Been using them for 48 years now. The black trays with bumps are cool but it doesn’t look like you can cut the pizza on them, which is what we do now. I’d hate to add that extra step…
They do make the same aluminum tray with raised bumps but they are pricey.
I use the Aluminum ones with nibs. They’re great. We use a large tray to cut the pies then just slide 'em on -easy. I just got some for our slice pies as well. Mine are flat on outer rim, the ones you show have a high edge. I’d think the high edged ones would be a little awkward.
We use the black with raised bumps like you posted, over a year in and no discoloration, people love them and talk about them all the time. You can cut on cardboard circle and slide in or cut on peel. I’ll make video and post how to slide
