In a mortar, pound the garlic with a pinch of salt to make a paste; place in a medium-sized mixing bowl. Put the coriander seeds, paprika, cumin seeds, thyme, cayenne and curry powder in a dry skillet. Over medium heat, cook, stirring, until hot and aromatic, about 30-45 seconds. Remove spices from the pan, put into the mortar, and grind to make a fine powder. Combine the garlic paste, spices, olive oil, lemon juice, parsley, 3/4 tsp salt, pepper and pork cubes. Toss well to coat completely and let marinate several hours, mixing occasionally.
Prepare grill according to manufacturer's directions. Skewer the pork. Grill over hot coals, turning every two to three minutes and basting with marinade, until well browned, about 15 minutes. 3 servings.
