Yeast breads refers to any bread leavened by yeast. This includes pizza dough, cinnamon rolls, and brioche loaf.
Active dry yeast and instant yeast are the most popular types of yeast used in home baking. Read this comprehensive tutorial for baking with yeast for consistent bread results.
Flour is a key ingredient in yeast breads. There are various types of flour available for baking. Be sure to use the correct flour specified in the recipe.
Other important ingredients include sugar, salt, and fat. Sugar helps to activate the yeast. Salt adds flavor and prevents the yeast from over-rising the dough. Fats include butter, eggs, and milk. Fats add flavor and contribute to a moist crumb.
For first time yeast bakers, I highly recommend starting with a very simple yeast recipe like this easy pizza dough.
