Lower Watt, increase time.
Yes, but some times the popping is just the food unfreezing. If the food is not burning and staying cold at the same time, then do nothing.
I wish inverter type microwaves were standard. The vast majority of residential microwave ovens only modulate on like a 10 second interval. So you put it on power setting 3 or 30 and it will pump out full power for 3 seconds then off for 10 seconds. This works for things like defrosting meat, but a bunch of foods will still start popping and drying out in those few seconds. Inverter microwaves modulate many times a second so they can warm much more fragile foods without searing them.
Or just don’t cook things in a raggedy bitch microwave. Use a grill, stove, oven, or whatever other better tools for the job.

Them: I wish microwaves were better

You: don’t use crappy microwaves then!

Yes

Yep. Same reason you don’t run your conventional oven at max for most food types.
This is a shot from Shazam staring Sinbad as the Genie. Great movie, used to watch it all the time in school holidays.
Not today, Mandela.
It’s spelt Mandala here
If you put a piece of tinfoil in the middle of what you are microwaving. The tinfoil helps keep the center hot and the temperature even.
Works with forks too
