Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius). Place a pan of oil inside to heat at the same time.

In the bowl of a food processor, shred the onions. Add eggs, and then shred the potatoes into it. (I use the Braun shredder blade.) Add water and mix together.

Remove the pan with oil from the oven and carefully pour the batter inside.

Place the kugel in the oven and bake for 20 minutes. Lower oven heat to 375 or 350 degrees Fahrenheit (190 degrees or 175 degrees Celsius) for a good two hours, or until golden brown.
