In a dry pan, toast all the Mandi spice ingredients over low heat until fragrant, then let them cool before grinding into a fine powder. Mix the ground spice blend with turmeric powder, red chili powder, and salt.
Rub half of the prepared spice mix onto the chicken drumsticks, along with 1 tbsp olive oil and lemon juice. Let the chicken marinate overnight to absorb the flavors.
In a deep pot, bring water to a gentle simmer to create stock. Place a stand inside and set a greased colander over it. Arrange the marinated chicken drumsticks in a single layer. Cover and steam for 25-30 minutes, flipping the pieces halfway through. Once cooked, remove the chicken and set aside, reserving the flavorful stock for the rice.
Heat 1 tbsp oil in a pan and lightly sear the steamed chicken drumsticks until golden brown. Remove from heat and set aside.
