Finely chop the onion and squeeze out the juice. Set the onion juice aside for shaping the kofta later.

Season the ground beef with salt, black pepper, kofta spice mix, baking powder, and cornstarch.

Mix the ingredients very well until the mixture becomes stringy and sticky.

Refrigerate for 30 minutes.

Shape the kofta by dipping your hands in the reserved onion juice and forming the meat into logs.

Place the kofta on a baking tray and bake in a very hot oven at high temperature until nicely browned.

Heat a piece of charcoal until red hot, place it on a piece of foil in the center of the tray, add a tablespoon of oil, and cover the kofta well to let it absorb the smoky flavor.
