If even one person here doesn't yet have a fast-reading food thermometer I have to evangelize for them here. Good ones that instantly read used to cost like $75, and the cheap kind would take literal minutes to arrive at the real temp, but I think someone in China figured out the secret and brought the price down to like $14. Mine has a magnet and I keep it right next to the microwave and air fryer. It has made it tremendously easier to get food correctly heated through, in both devices.
The other thing I believe in strongly is, for most things, using 40-60% power and heating the food about twice as long as your original instincts say, for more even heating.
