In a large bowl, combine the minced meat, salt, garlic, cumin, black pepper, ginger powder, paprika, coriander powder, fenugreek powder, grated nutmeg, clover powder, cardamom powder and oil. Make sure everything is infused evenly together. Transfer the meat to a rimmed sheet and spread it to a thin even layer. Place it in the refrigerator, uncovered, on a shelf alone to avoide transference of flavor, yes please, uncovered for 24 hours in the refrigerator, give a quick stir ever 5 hours, have passed; keeping the meat unocovered will help the meat dry out which is exactly what we want.
