Khaman and Dhokla are both traditional snacks from Gujarat, but they differ in the following ways:
1. Khaman is made from chickpea flour and is usually softer and fluffier. It is also typically yellow in color due to the use of turmeric.
2. Dhokla is also made from a fermented batter of rice and urad dal (black gram). It is slightly spongier compared to khaman and can be served in various flavors.
Thus, the key difference lies in the ingredients and texture of the two snacks.
