Claimed to be originated from Laos, Som Tam Pu Ma is a zesty salad that will make you feel like you have a mouthful of the tropics. It's created by mixing together julienned raw papaya with the raw blue crab, chopped tomatoes, Chinese long beans, peanuts, bird's eye chillies, yardlong beans and garlic. Coconut palm sugar, fish sauce, salt, and lime juice are added to season the salad. The chunks of the raw blue crab, the sweet and sour seasoning and the pleasing crunch from the papaya and the peanuts make such a wonderful experience.
