If you are trying to convert an oven recipe to make it for the microwave in the DCB, how would you adjust the time. The recipe calls for 350 degrees for 1 hour... in microwave on high, for half the time or a quarter or what? Need a sweet potatoe recipe for Christmas and know that my MIL's oven will be full of other stuff, so want to convert for the microwave so we don't have to wait until the last minute to go (after the sweet potatoes are done baking).... TIA!
