Guest post from Pitmaster Mubeen Makda:
Regular beef mince/ground (not lean), also known as Keema
Ginger and garlic
Raw onion, sliced almost like powder
Hara (or Garam) masala
Mince all above ingredients and mix it with Keema (ground beef)
Add salt, crushed pepper & hara masala. You can substitute with Garam masala as well.
Leave it overnight in the fridge. Make small balls and grill :))
Grill on a flat surface or put it on top of a foil in the grill. This will further retain the flavor.
