French Fried Onion Rings

4 Large Bermuda onions, in 1/4 inch slices
2 Cups milk
1/2 Cup flour
Salt to taste
Separate the onion slices into rings. Put them in a shallow dish and poor milk over them. Soak for 30 minutes, turning once or twice. Mix the flour with a sprinkle of salt, dip the rings into this mixture, coating them all over. Heat oil to 370 degrees and deep fry the rings several at a time until golden on both sides. Pat free of oil, keep warm while frying the rest, and sprinkle with more salt, if desired, before serving. 8 servings.
