Question

Fill in the blanks - Idli dough rises because of _____________.

Answer 1

Idli dough rises because of the multiplication of yeast.

Answer 2

Idli dough rises because of the growth of yeast cells.  

Explanation:  

• 'Yeast is a 'fundamental component' for making bread and other savory baked goods. Yeast is added to warm water, where yeast reproduces and builds a colony.
• They use the 'sugars present' in the bread and secretes a liquid along with carbon dioxide as well as ethyl alcohol. The gas and alcohol help in rising the bread.
• The bread becomes 'very soft and fluffy' as a result. When the bread is baked, the alcohol evaporates off and the resultant bread tastes fine.
