Soak dried shrimp and mushrooms separately in cold water for 10 minutes, then drain and clean. Remove stems and halve or slice mushrooms. Heat half of the oil in a frying pan or wok, add onions and stir-fry 2-3 minutes. Lower heat slightly, add shrimp and mushrooms and cook, stirring, until only residual moisture is left and oil spatters when in contact with moisture. Remove from heat. Heat rest of oil in a small saucepan, add shrimp mixture, soy sauce and wine or sherry and stir-fry 1-2 minutes. Add water and simmer 20 minutes or until water has nearly evaporated. Meanwhile, cook noodles according to packet directions or instructions on these pages. Drain, rinse quickly under cold running water and drain again. Reheat all ingredients together and serve.
