Pumpkin Pancakes

In advance of Halloween, though I would pass along a tasty and fun recipe for pumpkin pancakes. Hope you enjoy.
2 cups all-purpose unbleached flour
2 tablespoons sugar
4 teaspoons baking powder
1 teaspoon cinnamon
3/4 teaspoon salt
1-1/2 cups milk
1 cup canned pumpkin
4 eggs, separated
1/4 cup melted butter
Combine the flour, sugar, baking powder, cinnamon and salt in a mixing bowl. Mix together the milk, pumpkin, egg yolks and butter in another bowl. Using a hand-held electric mixer or a wooden spoon, beat the mixture until well-blended. Add the milk-pumpkin mixture to the flour-sugar mixture and, using a wooden spoon, mix just enough to moisten all ingredients. (Overmixing at this point will create pancakes with a rubbery texture.) Using clean beaters and bowl, beat the egg whites until they are stiff but not dry, then fold them into the batter. Spoon the batter onto a buttered or oiled hot griddle. Fry the pancakes until the tops look dry and small bubbles appear on the surface. Turn the pancakes and fry until second side is golden-brown. Serve with hot maple syrup. Yields approx. 30 four-inch pancakes.
