Heat a wok over medium-high heat. Add the Laksa Curry Paste and cook, stirring, 2 to 3 minutes. Pour in the chicken stock, fish sauce, soy sauce, sugar, lime juice and coconut milk and stir well. Bring to a simmer, and then reduce the heat and cook for 5 minutes. Stir in the shrimp and cook until just cooked through, about 2 minutes. Meanwhile, bring a large pot of water to a boil and cook the noodles until al dente, about 3 minutes, and then drain and rinse under cold water to refresh. Add 3/4 cup of the bean sprouts to the shrimp mixture. Taste and adjust the seasoning with salt and cayenne pepper. To serve, divide the noodles between 2 large, shallow bowls and ladle the shrimp and broth over each. Garnish with clusters of cilantro and basil, sprinkle the remaining sprouts over the top and serve immediately.
