Notes
1. Dry cilantro leaves well before using. If they are wet, your dough will be very wet.2. Don’t skip the steaming step as it helps the vadi hold its shape while air frying.3. You can prep by making and steaming the vadi ahead of time. Just cut and air fry when you are ready to eat.4. Add ¼ tsp. Baking soda or ½ tsp. Eno if you want your kothimbir vadis to be fluffier. These are denser inside and crisp outside.5. You can add other greens like parsley, spinach and methi or fenugreek leaves to the dough as well for variety. Even grated carrots is nice here.
