I've had the joy of visiting Thailand numerous times in recent years. During one visit, I fell in love with a vegetable they call pak boong, or morning glory. It's also known as water spinach, and I must confess it may be slightly harder to find in the states. Ask around, though. Asian markets usually have it and you can, of course, order it online. Use hearty varieties of chinese broccoli, watercress, or bok choy so you can learn the technique. This dish is about putting raging heat under your command.
