1/2 lb raw prawns, shelled & deveined
2 garlic cloves, chopped
1/4 cup & 1 tsp fish sauce
freshly ground black pepper
2 tbs peanut oil
2 shallots, thinly sliced
3 stalks lemongrass, white bulb crushed
1 large ripe tomato, cored, seeded and cut in wedges

Dilute the tamarind concentrate with 1/4 cup warm water. Halve each prawn lengthwise. In a bowl combine the shrimp, garlic, 1 tsp of the fish sauce and pepper to taste. Set aside for 30 minutes.
Heat the oil in a large saucepan. Add the shallots and lemongrass and sauté briefly without browning. Add the tomatoes and sugar and cook over a medium heat until slightly soft. Add the pineapple and bamboo shoots and cook, stirring, for about 2 minutes. Add 5 cups of water and bring to a boil over a high heat. Stir in the tamarind water, salt and remaining fish sauce. Reduce the heat to medium and simmer for 5 minutes. Stir in the prawns, chili and bean sprouts and cook for 30 seconds. Add the scallion and mint. Remove from the heat and discard the lemongrass. Ladle into a serving bowl and serve at once.
