Besan, buttermilk (or 1 cup yogurt + 1 cup water), turmeric powder, ginger-green chili paste, salt and oil
Whisk besan, buttermilk, turmeric, chili-ginger paste, and salt into a smooth batter. Cook on low heat, stirring continuously until thick.
Spread a small portion on a plate. If it peels off easily after cooling, it's ready. If not, cook for a few more minutes.
Quickly spread the cooked batter on a greased plate or back of a steel tray while it’s still hot.
Once cooled, cut into strips and gently roll them into tight spirals using light hands.
Heat oil, add mustard seeds, sesame seeds, curry leaves, and green chilies. Pour the tadka over the khandvi rolls.
Garnish with fresh coriander and grated coconut. Serve with green chutney for a delicious Gujarati treat!
