Then using hand or some pestle first make small pieces and add them into mixture jar. Finely grind them. If any chunks remaining, then re-grind them.
Mix the sugar powder very well into churma mixture. Meanwhile heat the ghee in a small pan.

Add the hot ghee into churma ladoo. The ghee is hot enough that bubbles are generated and you will get texture into mixture. First add little ghee, if bubble is not generated, heat ghee again and verify the texture.
Once you add ghee, then only cardamom and mix all..

You can use ladoo mold to make ladoo. Or take some churma mixture and give a round ball shape using hands. Immediately spread poppy seeds so that they will stick to churma ladoo.
