This is the basic recipe that I use. An easier cooking method is to use the microwave as long as you have one with a rotating tray. Line the tray with paper towels, about 12 of them so that they overlap and they tray has no areas left uncovered. Place the rumaki around the edge of the tray in a circle. Microwave on high for 15 to 20 minutes, the time really depends on your microwave so watch them carefully. The paper towels absorb the grease.
