Grease a plate with ghee.
Put ghee in saucepan and add green cardamoms in it. It should not be too hot or ghee will burn.
Add powdered milk. When milk turns brown and crumbly, add eggs.
Mix well and add whole tin of condensed milk.
When it becomes totally dry and starts sticking to the cooking spoon add walnuts and mix.
Take it out and set it in the greased dish/tray.
When cooled, cut into cubes.
Can put in fridge as well and it will stay good for a long time.
