2. Generously dip the cutlets in eggs. means really bath them in the egg. This will ensure that the cutlets are well sealed and there will be less chance of breakages while frying.
3. While coating in breadcrumbs, just give a light coating. Overcoating breadcrumbs would make your oil "dirty" very fast.
