I haven't had time to get to the Asian grocery store and I've been short on time so I chose this simple recipe. There's a more elaborate Khmer recipe I'm going to try when I have some time.
Cooking fish sauce stinks to high heaven but the resulting dish is very good.
Look for young unwrinkled ginger otherwise you'll get the "cat hair" effect.
