From Food Editors' Favorites. Joan Nathan submitted this. The blurb said "Recently, when demonstrating how to make potato latkes for Hanukkah, I discarded my recipes and put together a ratio of potatoes to other ingredients. I call it the potato pancake principle". You can use 1 potato plus a beet or a zucchini instead of 2 potatoes. *Note-Joan recommends making them early in the day, letting them drain all day long (do not refrigerate), then crisping again just before eating by putting them on an ungreased cookie sheet in a 350 degree oven until just warm.
