Top-ranked recipe named "Fat Ronnie's Deep Fried Fresh Mushroom's"
Place buttermilk in bowl and set aside. Mix flour, salt, pepper, and baking powder in separate bowl. Heat oil at 375 for frying.
Coat mushrooms with flour mixture, dip mushrooms in buttermilk, and finally coat mushrooms with flour mixture again. Place mushrooms in hot oil and do not over crowd. Oil should be about 375 for deep frying. When mushrooms turn a golden brown remove and drain on absorbent paper towel. More salt may be added to mushrooms for your taste. Fried mushrooms should be served immediately for the best taste.
