To fry chicken, heat 1 1/2 quarts vegetable oil in large wok or dutch oven to 350f but do not overheat or chicken will burn! Use thermometer if necessary.
One piece at at time, dip chicken in marinade and then dry coat, pressing dry mix into chicken to make it stick. Coat every piece but its ok if some coating falls off be careful not to over bread.
Once piece at a time, shake off excess coating and lower into oil, don't drop or splash. Once all chicken is added, insure temperature doesn't dip below 325 or go over 375.
