Prik nam blah (พริกน้ำปลา) is about as ordinary on a Thailand dining tables as is a bottle of ketchup or mustard at any good hot dog stand. Fortunately it's quite a bit easier to make than those western condiments. Just a little high-quality fish sauce and some of the good, very hot, Thai chilies that we call Prik Kee Nu. There are actually 2 types of chili that we use. The smaller variety called Prik Kee Nu Suan are so spicy that even most Thais don't eat them. Here we use the longer ones. But they are far from mild.
