In a small bowl mix together the lemon sauce ingredients; set aside in the refrigerator to chill giving time for the flavors to blend.
Preheat deep fry to 350F.
In a wide shallow dish mix together the bread crumbs, Cayenne pepper, and parmesan cheese. (I use a pie dish for this)
Place the flour in another shallow dish and salt and pepper it to taste.
In a small bowl whisk or beat the eggs until well beaten. (Not frothy but well combined)
To coat the fillets, roll them in the flour to lightly coat, and then dip them in the beaten eggs; then roll them in the bread crumb mixture pressing lightly to coat.
Deep fry each fillet until golden brown, drain on paper towels and serve with the lemon sauce.
