Add a tablespoon of ghee and 4 tablespoons of milk to a saucepan. Warm it lightly. Then add a cup of milk powder to a bowl. Pour the warm milk into it and knead to a firm dough. If it is too sticky, add more milk powder as needed. Store it in the fridge and let it firm up. You can then grate or mash it and use it in recipes that call for mawa. I have shared the process on Instagram.
