Preheat the oven to 200F.

Place the beef cheek slices in one layer into a baking tray or pan. Drizzle 3 tablespoons of oil on both sides of the meat. Season the meat with salt, pepper, cumin, coriander, mace, cinnamon, and granulated garlic on both sides of the meat. Sprinkle the onions around the meat in the tray. Cover the tray with aluminum foil and bake in the oven for 6 hours, until the meat is cooked through, tender and falls apart. 

Transfer the beef onto a plate and shred the beef into medium sized pieces with a fork and place it into a mixing bowl. Add the onions and juices from the baking pan into the bowl. Mix the shredded beef with the onions and juices in the bowl.

Serve the beef hot and garnish with a few fresh sprigs of cilantro. Serve with matzo and fig jam.
