Toss the flour in a ziploc bag, add salt & pepper to suit your taste. Beat 2 eggs in a bowl add 2 tablespoons of water.
Put about 6 mushrooms in the egg mixture. Then drop them in the bag of flour mixture.
Shake and coat the mushrooms in the flour mixture.
I used a frying pan to deep fry my mushrooms. Heat the oil till hot (drop in a pinch of flour, if it sizzles, the heat is hot enough).Then lay the mushrooms in hot grease and fry to desired golden brown.
