During the heat of summer, noodles are deliciously refreshing when served floating in a bowl of ice water and accompanied by a chilled dipping sauce. For warmth in the winter, noodles are commonly served in piping hot broth. Whether in soups or salads, sautéed with vegetables, deep-fried, baked, or topped with sauce, noodles are delicious.
Quick to prepare, they provide the perfect solution when you have unexpected guests. In the time it takes for the water to boil and the noodles to cook, you can prepare a broth or sauce and a vegetable dish and voilà! In twenty minutes you can create a nutritious and satisfying meal.

Since most Japanese noodles are made with salt, it is not necessary or advisable to add salt to the cooking water. In a large pot, bring the water (about ten cups of water for every eight ounces of noodles) to a full rolling boil. Add the noodles a few at a time so as not to completely stop the boiling. Stir gently until the water is boiling rapidly again to prevent the noodles from sticking to the bottom of the pan. If too many noodles are added at once, the water will not quickly return to a boil and the noodles will be overcooked on the outside and undercooked on the inside. Also, using too little water will result in sticky, unevenly cooked noodles.

There are two acceptable methods for cooking noodles. The first method is quite basic. Simply bring the water in the pot back to a rapid boil once all the noodles have been added (as just described), then cook the noodles over medium heat until done. The second method is known as the "shock method". Once the noodles have been added to the pot and the water returns to a rolling boil, a cup of cold water is added to "shock" the noodles. When the water returns to a boil again, another cup of cold water is added. This is repeated three or four times until the noodles are cooked. No matter which method is used, noodles should be tested often to avoid overcooking. A properly cooked noodle should be slightly chewy. When broken in half, the noodle should be the same color throughout.

Once cooked, immediately drain and rinse the noodles in two or three cold-water baths or under cold running water to prevent further cooking and to keep the noodles from sticking together. When they have cooled enough to handle, drain and set aside until ready to assemble your dish. If reheating is necessary, place individual noodles in a strainer or colander and submerge in a pot of boiling water until just heated. Drain well and serve.

The noodle cooking water can be reserved, allowed to sour slightly, and then used as a natural leavening agent in breads, muffins, and pancakes.
