Microwave Power vs Time

ovens. Mine is more powerful but it's a Panasonic so the power level
can be reduced in 10% increments. For small changes, is the
relationship between power and cooking time nearly linear so it would
not make any difference whether I decrease power or time by 10%?

1. You didn't state how many watts your microwave is.
2. Seems bazaar they'd base cooking times on 1100 watts. Aren't more
microwaves under 1000 watts than over?
3. What's wrong with your regular oven?

In my experience these things are about linear, but they get nonlinear
for very short times.

At least for my oven, the different power levels (10 in my case) are
gotten by turning on the magnetron for different times, 10%, 20% to
100%, so they are no doubt linear except perhaps for very short times.

It's not bizarre; most microwaveable meals specify the recommended heating
times and power level based on being tested in a certain wattage MW. 1100
is pretty standard as stated on the packages. This person says they can
step theirs down to 1100 so that's what I'd suggest doing. And I'm guessing
this person doesn't want to use the regular oven because they bought
microwaveable food.

But if you read the box directions they'll have you believe that
you'll automatically die a horrible death if you don't microwave the
food to death! I'm on my own this week so I stocked up on lean
cuisines and I made the mistake of trying their 'potstickers with
rice'. The instructions on the box said to nuke it on high for eight
minutes! So I did... and when I opened the seal I had rice glued into
a solid lump, and strangely dried-out dumplings. I have no idea why it
needed to cook twice as long as all the other lean cuisines... I guess
the dumplings were not pre-cooked. Either way it doesn't matter - they
were only vaguelly edible and the rice was a total washout.

Many of my frozen dinners can be prepared in the oven but I don't want
to take the time, especially at lunch.
And although I'm not expecting gourmet results, I want my fast lunch
to be as good as it can be;
since there's a choice of regulating either power or time I thought
I'd check out what others think.
Thanks!

It matters more for frozen food. Ice does not absorb microwaves as
well as water. At first this doesn't matter, since the microwaves just
keep bouncing around until they get absorbed. Since they travel at
186,000 miles per second, Joe and Susie Average aren't going to notice
this. However, as soon as any ice melts, now the microwaves are getting
absorbed more in that location. This is often in the corners, or food
that absorbs more. Thus, part of the dinner gets burned, while some is
still frozen. This is why most microwave ovens have a defrost setting.

That's what I thought. However, this site shows about a third of the
Panasonic ovens *over* 1200 watts!

They only travel at lightspeed until they hit the food. At that point
they slow down of course :)

Women generally aren't good at math. Many of the Walmart jokes I get

Pretty linear.
Ignore the directions though. I sometimes make Stouffer's for lunch at work
and we have a 1200 watt MW. If the directions say 7.5 minutes, it is
usually done in 4.5 to 5. The thick things like a lasagna though, need
longer times at lower power setting, or a lot more standing time. It cooks
faster if you take it out about half way and cut it down the center and make
an opening. In any case, I've never go near the times on the box.
bobnew...@yahoo.com
Thanks! This seems to be the consensus. I always reduce the time,
just not as much as you. And I do get overcooking at corners. Now I
know.

I have a countertop Panasonic rated at 1350 watts. The power is linear,
not pulses of 100% to achieve the power setting. I have found that for
prepared frozen foods, the results are far better if I reduce the power
setting to 70% (945 watts) or 80% (1080 watts), rather than adjusting the
time. Sometimes speeding things up is not the most desirable.
When I cook most frozen vegetables, I use 100% power to bring to a boil,
then reduce to 20-30% to simmer until done. It takes a bit more time, but
I like the results far better.
One thing the full 1350 watt power excels at is microwave popcorn. There's
never an unpopped kernal and none are ever burned.
My over the range microwave is rated at 1000 watts and uses pulse
technology. I generally reserve using it for items that work best at full
power or on the keep warm setting.
Given the choice, I will usually choose the Panasonic every time. The
cooking is much more even.
One other thing, the Panasonic is almost magical at defrosting anything
without actually cooking the edges or perimeter before the item is fully
defrosted. I can't say that of the pulse technology. Both m/w units have
sensors.

They're still at lightspeed, but lightspeed is different because of the
different medium. That's why refraction occurs.

No. The speed of light is a constant. In a vacuum.

But we're not talking about microwaves in a vacuum. We're talking about
microwaves in air (not a vacuum), and then in food (not a vacuum either).
The speed of electromagnetic radiation (including both visible light and
microwaves) is dependent mainly on the density of the medium through which
it travels (as well as some other properties of that medium).

Just take the package directions as a guideline rather than Holy Writ, and
learn that all frozen dinners (even from the same brand) are not created
equal. Write that one off as a loser.
Oh, and just a suggestion but learn to cook a few simple, quick dishes and
you'll be free of Lean Cuisine forever. Lots of things you can throw
together in half an hour or so--real pot stickers believe it or not is one
of the possibilities--google "pot stickers" and you'll find a bunch of
recipes. Basically just a spoonful of meat on a wonton wrapper and then fry
it up for a bit, add some water to the pot, and boil until done. The real
variation is just what spices you put in the meat and what meat you use.
And if you can do those you can do pierogies and wonton and a few other
things. The rice to go with them you can do on the stovetop but it takes
practice. A Black and Decker steamer does a superb job for cheap, or for
more bucks the Japanese have some really marvelous computerized purpose-made
rice cookers, and either is fire and forget--add water, add rice, turn the
knob, and you don't have to do anything with it until it dings.
