In a large sauce pan or pateeli, pour in a generous amount of oil and fry the onions.
When the onions turn transparent, add red chilies and garlic cloves and fry all of them until they turn golden brown.
Remove the onions, garlic and chilies from the oil and let them cool down
In a grinder or a blender, blend the fried ingredients along with yogurt and raw papaya paste.
Add the mixture to the ground beef.
Add roasted cumin seeds, salts, and 1/4th cup of the oil used in frying the masala.
Once the meat has been marinated, keep it overnight in the fridge.
Add the meat in a pot and allow to cook at medium flame. Ideally keep an insulation pan or a griddle below the pot. This is called as "dum dena" or cooking with insulation.
Your meat will take somewhere around 40 to 60 minutes to release water and cook entirely.
Once you see the water drying up and your keema (meat) binding together, add a piece of charcoal to your keema to give it the smoky flavor it needs.
After 5 to 10 minutes of smoking the keema, turn off the flame
Serve with lemons and onions garnish. It goes well with rotis, parathas and potato curry on the side
