Preheat the oven to 375 Deg. F.
Grate the peeled potatoes and onions either by hand or in a food processor. Alternate between grating the two, as the onions help prevent
the potatoes from going brown.
Mix well and pour into a sieve, pressing down on the potato and onions to get rid of any excess liquid.
In a large bowl, combine the potatoes and onions with the eggs and mix well.
Add a tablespoon at a time of the flour or matzo meal and stir thoroughly.
Add the salt, pepper, chicken stock powder and baking powder and mix well.
Pour the batter into a lightly oiled roasting pan, drizzle the oil or schmaltz over the top and bake, uncovered, for about 45 minutes to 1 hour or
until golden brown. You can reduce the heat and allow it remain in the oven until ready to serve. There's nothing like a fresh, crispy kugel.
