In a deep saucepan, heat one cup of water until it boils, add the ghee and salt, lower the heat, add the rice flour quickly with constant stirring until all of the water is absorbed, cover with a tight-fitting lid and steam for 10 minutes.
In this step, the dough is rested while the poppy seeds are roasted in a separate pan for 1 minute. The freshly grated coconut & grated jaggery are roasted for 5-7 minutes, until the jaggery melts and turns into a sticky, thick filling, after which the cardamom powder and the nuts are added.
Transfer the warm rice dough to a large platter, moisten hands with water/ghee and knead thoroughly for 5 minutes to get a smooth, completely pliable, crack-free rice ball.
Fill the modak mould with a little bit of the smooth rice dough, smooth it out with your hands and press it against the sides so that a hollow is formed, and then fill in this hollow with a little bit of the cooled coconut mixture.
Cover the bottom base of the mould with a small amount of excess rice dough, open the mould slowly to take out the shaped modak, and repeat step 5 for the remaining rice dough; then steam all the modak for 10-12 minutes.
