Boil potatoes for 20-30 minutes or until cooked. (Use a pointed stick to test.) Peel it and mash until smooth. After that add dill, pepper, salt and grated mozzarella cheese. Use a spatula to combine.

Form the mixed potatoes into a small ball (34 g/ each). Push a piece of mozzarella cheese (7-8 g/ each) into the center of the small ball. Dust the balls with crispy flour, bath with eggs and coat again with breadcrumbs.

Preheat the wok, add olive oil. Put the potatoes cheese balls to fry. Fry until turn to golden brown, scoop up, drain and line with kitchen paper. Now ready to serve.
