Prepare the Spiced Paste: Grind the ginger, garlic, green chillies, cumin seeds, and fresh coriander stems into a coarse paste
Make the Batter: In a mixing bowl, add the Thalipeeth Bhajani flour. Mix in your prepared green chilli paste, chopped coriander leaves, sesame seeds, crushed carom seeds, turmeric, coriander powder, hing, and salt.
Add the Tanginess: Squeeze half a lemon into the mixture. You can also use tamarind pulp. This is essential for the taste!
Mix with Water: Gradually add water and a few drops of oil, mixing well to form a smooth, spreadable batter. It shouldn't be too runny or too thick.
Prep the Leaves: Wash the Colocasia leaves gently and wipe them dry. Cut off the thick stems at the base. Gently roll over the thick veins on the back of the leaf with a rolling pin to flatten them out.
Apply the Batter: Place the largest leaf upside down on a flat surface. Spread a thin, even layer of the batter all over it. Place another leaf on top and repeat until you have a stack of 2 to 3 leaves.
Roll Tightly: Fold the outer edges inwards, and tightly roll the stacked leaves into a firm cylindrical log.
Steam the Rolls: Grease a steamer plate with a little oil. Place the rolls on the plate and steam them covered on a medium flame for 15 minutes.
Cool and Slice: Once steamed, take them out and let them cool down completely. Once cool, use an oiled knife to cut the log into slices (vadis).
Shallow Fry: Heat oil in a pan on medium heat. Shallow fry the slices until they turn beautifully golden brown and super crispy on both sides. Serve hot!
