My 27 year old microwave oven was down below 400W output and taking a long

So, I went out and bought a 1100W one.
Big mistake.
It works fine on coffee, but WAY overcooks small stuff.
Yes, it has a power level setting, but the on-time is 15 seconds
and they modulate the off-time.
I tried to heat a frozen hamburger patty. It boils the liquid around
the outside for 15 seconds, but the inside is still frozen.
This really messes up the cheese stuck to it. If I leave it in
the frozen burger, it comes out awful.

What are my options for reducing power?
Yes, I can stick in a pot of water to absorb energy, but I'm
looking for a more elegant solution.
I assume there's nothing I can do on the primary side, cause of the
filament voltage requirements.
Assuming I can find a switch that can take the voltage and current,
can I switch the value of the big cap? Not much else in there to play with.

Alternatively, there's stuff they put in the bottom of microwave popcorn
that heats up from microwaves. What is that stuff? Maybe I can find a
pan with that in the bottom to average out the energy over time.
There's a "as seen on TV" serving plate that you heat in the microwave.
It's made of granite. What is it in the granite that gets heated?
IF I could find a square of floor tile in ceramic or granite, ceramic is
more easily available, I could stick one of them in the bottom of the oven.

Suggestions?

RTFM to see how to set the cook power.
Amazing!!!
RTFM reply when I stated EXACTLY how the power setting works.
How about RTFOP?


Then stick a damn glass of water in the oven to adsorb some of the
energy.

You're just DETERMINED NOT TO READ the original posting...where I
mentioned that too.
Although, I'd not considered adsorption as a relevant process.
