Question: how do you cook a potato in the microwave with a ziplock bag?
Answer: I took 4 or 5 potatoes about the same size, put them in a microwave safe ziplock bag. (A few potatoes were larger than others so I cut them in half, so all potatoes were about the same size.) I then zipped it shut and put the bag and potatoes into the microwave. I cooked them on high for 10 minutes!
