Sanjay is preparing batter to make dhoklas. Which of these microbes should he add to his batter to make it fluffy and airy?

Options

A. Lactobacillus
B. Penicillium
C. Rhizobium
D. Yeast

Answer

To answer the question about which microbe Sanjay should add to his dhokla batter to make it fluffy and airy, follow these steps:

### Step-by-Step Solution:

1. **Identify the Purpose**: Sanjay wants to make his dhokla batter fluffy and airy. This requires a fermentation process that produces gas.

2. **Understand the Role of Microbes**: Certain microbes can ferment carbohydrates and produce gases. The most common microbes used for this purpose in cooking are yeast and bacteria.

3. **Choose the Right Microbe**: Among the various options, yeast is known for its ability to produce carbon dioxide (CO2) during fermentation. This is crucial for making the batter rise and become fluffy.

4. **Explain the Process**: When yeast is added to the batter, it undergoes aerobic respiration in the presence of oxygen. It uses carbohydrates (found in the batter) as fuel and converts them into carbon dioxide and alcohol.

5. **Result of the Process**: The carbon dioxide gas produced gets trapped in the batter, causing it to expand and become airy and fluffy. This is the desired outcome for making dhokla.

6. **Conclusion**: Therefore, Sanjay should add yeast to his batter to achieve the fluffy and airy texture he desires for his dhokla.

### Final Answer:
Sanjay should add **yeast** to his batter to make it fluffy and airy.
