I love Nam Pla Prik! I make a northern version which includes, besides the chillies, chopped lime leaves, finely chopped or crushed garlic, squeezed lemon or lime juice, crushed and chopped lemongrass, chopped cilantro, finely chopped ginger and/or galanga, and rarely, a wee bit of mussaman, red, or green curry paste. I usually use Thai rat chillies or finely chopped serranos. It is intense so I always taste for the right balance of ingredients and nam pla. I put this in Green Papaya Salad (Som Tum), Tom Yum or other clear soups, and non-coconut cream dishes. It is perfect on rice, especially sticky rice.
