Today for lunch I had some frozen burritos. The instructions were to heat them at 50% power for 2 minutes and then full power for one minute in the microwave. Alternatively you could cook them for 40 minutes in the oven.
40 minutes. Seriously? Nearly an hour to defrost some food? How did people function 50 years ago? Granted, I'm sure the oven open doesn't include the nice frozen surprise the microwave option gave me, but still when you factor in time, electricity (or gas) to cook 2 crappy frozen burritos I don't see how they did it.
I guess the answer is that they didn't have crappy frozen burritos to cook..they just made burritos..
