Combine the breading ingredients in one shallow bowl, adjusting the amount of cayenne to fit your tastes. This recipe is only moderately spicy.
Combine the milk mixture ingredients in another shallow bowl, adjusting the amount of hot sauce to fit your tastes.
Fill a fry pan with just enough oil to cover the fillets. (Do not add the fillets yet.)
Warning: Do not flick more than one tiny drop of water onto the oil. Oil and water do not mix. If you add any significant amount of water, you will create an explosion.
To test if fish is fully cooked, remove a piece from the oil, and cut into it with a fork. If the white fish meat flakes, it is ready to eat.
We use Frank's Hot Sauce because, unlike most brands of hot sauce, it is free of artificial preservatives. We eat our fried fish with MSG-free ranch dressing.
