When I was a kid my mom made potato pancakes out of leftover mashed potatoes. I really liked them, but never paid any attention how she did it. Now I am getting so bored with our sides that I thought about the pancakes, and tried a couple ways, but they were a disaster. I got some boxed mix, and it was okay, but . . . I tried taking some and mixing an egg in them, then fried them, but that wasn't very good, either. What should I be doing?
