Pound garlic and salt with a mortar and pestle to make a paste, set aside. In a dry skillet heat the coriander seeds, paprika, cumin seeds, thyme, crushed red pepper and curry powder until hot and aromatic, about 30 seconds. Remove from pan and put the mixture in a spice grinder or use a mortar and pestle to grind mixture to a fine powder. In a large bowl, combine garlic, spices, olive oil, lemon juice, parsley, 3/4 teaspoon salt, pepper and pork cubes. Toss well to coat completely and let marinate in the refrigerator for several hours.
