In a bowl blend the yogurt, the lemon juice, the salt and the garam masala until smooth. Add the chicken and mix well to evenly coat the chicken. Allow to marinate for 30 minutes.
Thread the chicken onto skewers and grill over medium heat until browned on all sides. Remove from the fire and keep warm.
In a ceramic mortar bowl add the ginger and garlic and grind it into a paste using a pestle.
In a skillet over medium heat add the cream, the ginger-garlic paste, the tomato paste and the salt and bring to a boil. Simmer with frequent mixing for 10 minutes.
Add the chunks of grilled chicken and simmer for 5 minutes longer.
Evenly divide the chunks of chicken with the sauce onto 4 heated plates. Garnish the dish with sliced almonds and coriander leaves.
