You can use any amounts of flour, bread crumbs and seasonings, depending on how many mushroom caps you are making. You can use whatever seasoning you prefer, garlic salt is good to use in place of the seasoning salt and garlic powder. Prepare as many mushrooms as you like. Make certain to use only FINE DRY bread crumbs, if you cannot find any fine bread crumbs, process the crumbs on the food processor until fine, soft bread crumbs will not hold on the caps.
