Mix the Ener-G Egg Replacer in a small bowl according to the instructions. Set aside.
Grate the potatoes and onion into a large bowl. You can use a box grater if you do it by hand. However, either a food processor or blender makes the task easier. If you use a blender, the consistency of the potatoes will be batter-like but the pancakes will be fine.
Add the remaining ingredients, except oil, to the potato and onion mixture and combine well.
Heat about three tablespoons of oil in a frying pan (the oil should cover the bottom of the pan) and drop the potato mixture into the pan, about 2 soupspoons of batter for each pancake. Flatten the batter to form pancakes. Add oil if needed as the pancakes cook. (You will have to add oil to the frying pan for each batch of pancakes.)
When the pancakes are golden brown, flip them. As soon as the pancakes are brown on both sides (and the potatoes are cooked), remove the pancakes and let them drain on a plate covered with a paper towel.
Serve warm with applesauce.
