"Alu Vadi" is made from Colocasia leaves (Patra Leaves).  
In Marathi it's called "Aluchi Pane".
It's a combination of Colocasia leaves and Besan (gram flour) with some spices.




Ingredients:
6 - 8 Patra leaves
1 1/2 cup Gram flour (Besan)
2 - 3 tablespoon Jaggery and Tamarind pulp (Soak Jaggery and Tamarind together in water)
1 tablespoon Red chili powder
1/2 tablespoon Garam masala
1/2 teaspoon Turmeric powder
1/2 teaspoon Cumin powder
Salt as per your taste

Method:
Wash the leaves. Remove the stalks and remove the extra veins from the middle. Keep it aside.
In a mixing bowl, add besan, red chili powder, garam masala, Cumin powder, turmeric, jaggery and tamarind pulp, and salt. Add water as per your need and make a thick paste.
Now take a leaf and place on a flat surface with the vein side facing you. Apply the paste.
Now take another leaf and place that on top of the first leaf in the opposite direction . Apply the paste.
Repeat this with at least 3 - 4 leaves.
Fold the leaves, little bit from both sides. Start rolling and make a roll.
Repeat this with other leaves too.



Steaming:
Take a big vessel. Add 2 to 4 cups water and let it boil.
Once the water started boiling, put one pot into that. Top of that place the other pot and keep the roll inside. (I'm using pressure cooker dabbas here).
Cover the lid. And let it steam for 20 to 25 minutes. Turn off the heat. Remove the rolls and let it cool for 5 minutes.
Cut them into bite size and keep it aside.

Now heat some oil for shallow fry the vadi. Adjust the oil as per your need (If you want, you can deep fry the vadi). Once oil is hot enough, place vadis into the pan and shallow fry them until it turns brown.


















Tips:
You can use steamer or pressure cooker for steaming.
Adjust your spices as per your need.
