I hate to reheat anything with flour in the microwave. I didn't want
to waste a lot of electricity to heat up the oven just for a couple
slices of pizza. Someone here had said that she reheating pizza in a
cast iron pan. I tried that. It did a great job on the crust, but did
nothing for the top. I tried putting a cover of it, and a dribbling a
little water into the pan before covering, but just couldn't get it right.

Today I tried it in the air fryer. I turned it on high and pre-heated it
for 5 minutes and then put in the pizza. I checked it after 3 minutes.
Perfect. The top was heated through and the crust had a great texture.
