Along with a can of coconut milk, this marvelous Green curry paste is the foundation for a fairly authentic Thai meal.  Follow the instructions--starting with a little oil, fry 2-4 tab. of the paste for a few seconds to bring out the flavor, add the coconut milk, meat and veggies.  Toward the end, add sugar to taste and, for tartness, add either fish sauce or lime juice.  Enjoy.  Depending on the time I have, I augment the sauce with kafir lime leaves, basil and fresh garlic and/or ginger.  But these additions not needed, but give the sauce a bit more zing.
