In Japan, soba noodles are found everywhere. They can be a popular, inexpensive fast food, an expensive exclusive specialty restaurant item, or made at home. Ramen are often added to a hot chicken or pork broth with various toppings, such as sliced pork, seaweed, kamaboko, scallions and even corn. Udon can replace soba in traditional soba recipes and some dishes even mix soba and udon noodles to give a variety of textures. Somen is often served cold in Japan. During the hot summer months it is even served in iced water with a dipping sauce. Somen is also added to stir fries and soups, including the famous Vietnamese noodle soup, pho.
