Adjusting cooking times for a 700-watt microwave
I'm renting a room where the owner is obsessed with energy savings, meaning that he makes me use a little 700-watt microwave that looks more like a child's toy than a real cooking device. I've always used 1000-1100 watt microwaves, so I could pretty much always follow the cooking instructions verbatim. Is there any simple way to re-calculate cooking times from 1100 watts to 700s watts? (To add insult to injury, I'm at an elevation of about 4200 feet....) Any tips appreciated!
