Next heat a pan to roast the black sesame seeds. As you saute constantly, it will splutter. Take it out and keep it separated from other roasted spices. Next roast the mustard seeds and transfer over a plate.
Now add some oil to the pan and roast the red chillies followed by coriander seeds. Transfer them over the plate. Next adding some oil, roast the spices like fenugreek, cumin and black pepper and combine them with other spices.
As the roasted spices cool down to room temperature, powder them finely in a mixer.
Next powder the roasted sesame seeds and take it out in a separate bowl.
Take the grated mango in a mixer and puree it along with 1/4 cup of water. Transfer the puree over a pan along with some oil.
