In a mixer jar, add 1 cup of rava and grind it into a fine powder. Set it aside.
Next, in the same mixer jar, add 1 cup of coconut and 1 cup of milk. Grind it into a thick and creamy paste. Set it aside.
Then, in a pan, add 3 tablespoons of ghee and the ground rava. Stir continuously and roast the rava on medium flame until it puffs up, being careful not to change its color.
Now, add 1 cup of sugar and mix well.
Then, add the milk-coconut mixture and mix thoroughly.
Stir continuously until the mixture binds into a dough and starts leaving the sides of the pan. Ensure that there is no moisture left in the mixture.
Transfer the mixture into a mixing bowl and spread it slightly.
Next, add 4 tablespoons of milk powder and 1 teaspoon of cardamom powder, and mix well. The mixture should still be slightly warm so that the milk powder easily blends in.
Now, take a small portion of the mixture and shape it into a peda.
Garnish the pedas with pistachios and shape all the pedas in the same way.
Serve immediately or store the pedas in the refrigerator for 15-20 days.
