In a bowl, mix together yogurt, hot sauce and garlic. Add chicken and marinate overnight in the refrigerator. The following day, mix together flour and cajun seasonings in a bowl. Remove chicken from the marinade and coat evenly in flour mixture. In a wok or deep fryer, heat oil to 370F. This can be achieved by heating over medium high heat. Use enough oil to cover 4 to 5 chicken wings at a time. Deep fry wings for approximately 8 minutes. Drain on paper towel. Serves 2 to 4
