Put shredded chicken into a bowl with the rice wine and ginger and toss lightly to coat. Set aside.
Bring a large saucepan of water to the boil, drop in the udon, stirring to prevent them from sticking. Bring back to the boil and cook for 3-5 minutes, until the noodles are just tender. Drain in a colander and rinse under warm water.
Divide the noodles between the serving bowls.
Pour stock, mirin and soy sauce into a saucepan. Bring to the boil, then stir in chicken and cook for two minutes, skimming as broth cooks.
Add snow peas and cook for one minute, just to soften snow peas a little. Taste for seasoning and adjust if needed.
Ladle broth with some chicken and sugar snaps over the udon noodles in the bowls and garnish with scallion.
