A microscopic fungus that multiplies rapidly in suitable conditions. It is a living organism and needs food, warmth and moisture to grow. These are provided when bread-type doughs are mixed.
Use: To make the dough rise in bread, rusks, rolls spiced buns and festive breads. When the yeast starts to work, it makes the dough rise and gives breads and buns their light texture. It can also be used when making pizza dough.
