Peel and slice onions. Slice fairly thick at least 1 /4 inch thick. Separate rings and use only the larger ones. Refrigerate until ready to use. Beat egg. Add rest of ingredients and mix well. In a large saucepan heat oil or shortening. Fill pan at least half full. When oil is hot enough dip onion rings into batter and cook until golden brown on both sides
