laborious. Most laminated doughs are leavened only by the steam created by the folding process. Danish pastry and croissant are sometimes considered a separate class of dough because they are made from laminated dough that is leavened with yeast. Choux pastry is a steam-leavened dough used for some types of sweet pastries, notably cream puffs, eclairs, tulumba and churros. Unlike most other pastry doughs, the ingredients for the dough are cooked on the stovetop before the dough is baked until achieving the consistency of a thick paste. Choux means cabbage in French. It's thought that the name comes from the shape of the cream puffs made with choux paste. Some dumpling and pasta doughs are similar enough that experts have difficulty distinguishing them, although dumpling is a very general category that overlaps with others like yeasted breads and batter biscuits. Varying the ratio of liquid and flour in a basic pasta dough may create a softer dough like that used for the German soup noodle spaetzle. Eggs are a very common addition to make the dough moist and easier to roll out. The dough can be filled or shaped various ways and boiled, baked, steamed or fried. Gluten free doughs like rice noodles and Japanese harusame noodles depend on the gelatinzation of starch for structure. Unleavened bread is made not only from wheat but in many cultures has been made from locally available starchy ingredients like corn, oatcakes and casabe de yuca since the earliest times. Sometimes meringue is considered a dough. The English recipe for "Satan Biscuit" dates to 1677, and earlier recipes are known by different names. Some included flour like a 1604 recipe for "white bisket bread". Techniques Techniques used in dough production depend on the type of dough and final product. For yeast-based and sponge (such as sourdough) breads, a common production technique is the dough is mixed, kneaded, and then left to rise. Many bread doughs call for a second stage, where the dough is kneaded again, shaped into the final form, and left to rise a final time (or proofed) before baking. Kneading is the process of working a dough to produce a smooth, elastic dough by developing gluten. This process is both temperature and time-dependent; temperatures that are either too hot or too cold will cause the yeast to not develop, and rising times that are either too short or too long will
