SUGAR NOTCH — The recipe starts with about 1,000 pounds of potatoes, fresh from their sacks. It includes some fresh onions, some eggs and … “No, no, no!” a long-time church volunteer named Jean cried out on Saturday afternoon, waving her arms to shoo a reporter away from what appeared to be bowls of spices ready to be added to the raw potato pancake batter in the kitchen at Holy Family Church. Jean did not want any secret ingredients to be revealed, lest some other cook whip up a batch of pancakes identical to the mouth-watering and amazingly not-greasy treats served at Holy Family’s annual Summer Festival last week. But she probably has nothing to worry about. Even if people knew how much flour or salt (if any) to use, they’d still need a small army of dedicated volunteers who aren’t afraid to roll up their sleeves and make potato pancakes from scratch. They’d need people like Bob Egan, of Hanover Township, who loaded the spuds into a peeling machine that used water, tumbling action and a coarse inner surface to clean the potatoes and remove their skins. “This is more than 100 years old,” he said, as the tumbling potatoes beat a rat-a-tat sound inside the mechanical peeler. A few steps away Dave Aftewicz, of Hanover Township, placed potatoes, one at a time, into a heavy metal potato cutter.
