First of all remove the stems of mushrooms and empty them from inside so that we can fill stuffing in them.
For stuffing
Boil and mash the potatoes and add all the spices.mix it well.
Now fill these stuffing inside the mushroom and place the mushroom with open sides facing each other and join them using a toothpick.(as shown in the pic)

Now dip the mushroom in batter and finally coat it with bread crumbs.
Now deep fry the mushrooms in hot oil till they are golden brown.
