Pour all the vegetable oil into a deep pan or deep fat fryer, and heat to 300 degrees F (160 degrees C.) Blanch the cut potatoes in the oil until soft, but not colored, about 4 minutes. Remove and drain.
Mix together the flour and the beer, then fold in the egg whites. Turn up the heat of the oil to 350 degrees F (180 degrees C). Dip the fish in the batter and fry for a few minutes with the chips until golden brown.
Drain on kitchen paper and serve with bread and butter, wally's (battered, deep fried pickles served with ranch dressing), and pickled eggs.
