The Italian chili paste veers this recipe away from the traditional, so use Sriracha if it's authenticity you crave. Us? We just wanted spicy noodles!
Bring a large pot of water to a boil. Add the noodles to the water and immediately stir gently. When the water returns to a boil, stir again and cook for 4 - 6 minutes. Turn off the heat and let the noodles sit for 2 minutes in the hot water. Drain into a colander and rinse under cold water until cool.
Meanwhile, heat the stock, shoyu, honey and chili paste in a small saucepan until simmering. Turn off and let cool slightly.
Serve the noodles with the sauce on the side, garnished with chopped scallions.
