2 cups hot mashed potatoes (If they are cold, they can be reheated in the microwave.)
2 tablespoons butter
1/2 teaspoon salt
1/4 teaspoon paprika
1/8 teaspoon cayenne (red) pepper
1/8 teaspoon celery salt
2 tablespoons parsley, chopped
2 egg yolks
1 tablespoon onion, finely chopped
1/2 cup flour
1 egg, beaten
1 cup fine bread crumbs
approximately 1/2 cup shortening
Mix together the potatoes, butter, salt, paprika, cayenne pepper, celery salt, parsley, egg yolks, and minced onion. Shape into 1-inch balls; then roll in flour, dip in beaten egg, and finally roll in bread crumbs. (If the potato mixture is sticky – and not very firm, skip dipping in the egg.)
Place the shortening into a frying pan, and heat until hot. (There should be about 1/2 inch of melted shortening. Add more if needed.) Drop balls into the hot shortening, then gently roll the balls with a fork until all sides are a light brown. Remove from heat and drain on paper towels.
