Soak the moong/mug daal in water for about half hour.
Make a smooth paste of the moong daal.
Mix moong daal paste, rice flour, salt, turmeric powder, red chili powder, sesame seeds, minced ginger and baking powder in a bowl.
Now, gradually pour water to the mixture and keep mixing. The batter should not be thin, else it will not coat the eggplant. I have added about 3 tablespoons of water. The amount of water needed depends on the amount of water that was used while grinding moong daal. the batter should be thick enough to coat the eggplant slices.
Take a pan and heat the oil.
Once the oil is hot, take a slice of eggplant, coat it with the batter.
Gently drop the coated eggplant in the hot oil.
Fry the eggplant on low-medium flame till it is golden brown on both the sides.
Take out the beguni and keep it on tissue paper to absorb the excess oil.
Serve the beguni with a steaming cup of tea.
