How to Make It
In a large pot of boiling salted water, cook the spaghetti until it is al dente. Drain the spaghetti and rinse under cold water until cool. Drain very well.
Meanwhile, in a food processor, combine the peanut butter with the lime juice, red curry paste, stock and 1/4 cup of the cilantro leaves and puree. Season the sauce with salt.
In a large bowl, toss the spaghetti with the peanut sauce, bean sprouts, scallions and carrot until well coated. Season with salt. Transfer to bowls and sprinkle with the remaining cilantro leaves and the peanuts. Serve with lime wedges.
