Kaeng pa (also called jungle curry or forest curry) is a traditional variety of Thai curry hailing from the northern, forested parts of the country. This curry is watery in consistency since it doesn't contain any coconut milk.
Other ingredients usually include galangal, garlic, chili peppers, kaffir lime leaves, green peppercorns, lemongrass, bamboo shoots, and Thai eggplant. Traditionally, this curry was prepared with wild boar, but nowadays it's mostly prepared with chicken, pork, or firm-fleshed white fish.
