In a large bowl, take grated cheese. Add finely chopped onion, ginger and coriander leaves to it.

Now add chilli powder, chaat masala, dry mango powder and salt as per taste. Mix everything well and keep aside for a while.

Take medium-sized mushrooms. Carefully cut them in the middle. Now take the prepared stuffing and pour it into the mushroom cavity.

Join 2 mushrooms while keeping the stuffing side intact.
Secure with a toothpick. This is very important, otherwise there is a chance of the cheese melting during deep frying.

Cover from all sides with cornflour slurry.
Then coat the mushrooms in breadcrumbs. Alternatively, you can also use rava.

Repeat dip in maida-corn paste and breadcrumbs again. Double coating is very important, otherwise there is a chance to melt the cheese during deep frying.

Now freeze the coated mushrooms in the freezer for 15-20 minutes. This is an extra precaution for the cheese to melt.

Heat the oil. Meanwhile, dust off the extra bread crumbs. Carefully place them in medium hot oil.

Fry them till they are golden brown. Drain and place on an absorbent paper.
Serve cheese stuffed mushrooms with tomato ketchup or as the case may be.
