Oh... thats where you are going wrong, when reheating pizza it is best to use a pan, although the base may get crispy. The oven works quite well too. Sure they take longer but tastes so much better!
I can't wait for my iot pan and stove respectively tell their manufacturers how often i'm reheating pizzas. Maybe my iot stove fan will get there first. All way after my iot fridge ofc called home to tell me to buy more pizza.
I can totally imagine a future iot fan to have chemical sensors so that it can send a "fingerprint" of the food you're cooking ...
An air fryer works wonderfully to reheat pizza or anything else involving bread. If it's something thick like a sandwich, I'll give it a low power preheat in the microwave first.
