Traditionally pancakes made from potatoes. But why not make them out of beets? After all, we are preparing a pellet-type pancakes from zucchini, squash. Of course, potatoes are still needed, otherwise too bright, so the beet will taste. Pancakes will turn out too sweet. Can't hurt, and greens. I did not add the onion, although once prepared, thought he would not hurt here. With two tablespoons of flour my dough turned out watery, but usually this amount I add the flour so much. Apparently, it all depends on what kind of potatoes. So the options at your discretion. But more than three spoons just do not need.
