In a bowl, mix milk, eggs and 1 tablespoon of salt..add chicken pieces and cover. Marinate atleast 4 hours, but better if overnight.
In another bowl, mix flour, powdered sugar,4 teaspoons salt and 1 tablespoon pepper. Add some chicken pieces to a large ziplock bag, add some flour mixture and shake to coat, fry in batches, 375 degrees deep fryer or large dutch oven. it only takes 3 or 4 minutes, drain on paper towels or wire rack.
For honey mustard sauce, mix the mayo, mustard, garlic powder, vinegar, honey and paprika in a small bowl..cover and put in fridge. I usually make this the night I marinate the chicken so it has a chance to blend together.
