To begin making the Vellai Dosa, in a large bowl, dissolve the powdered jaggery along with 1/2 cup water and allow it to rest for 30 minutes. After 30 minutes, strain the jaggery water to remove impurities.

Add the wheat flour to the strained jaggery mixture and stir continuously until there are no lumps. Add remaining 2 cups water and mix to make a smooth batter. Toss in the cardamom powder and mix well. 

The next step is to cook the Vella Dosa on a skillet. 

Heat a skillet on medium heat and pour a ladleful of batter on the skillet. Swirl the pan in a circular motion to spread the batter around to make a thin crepe like dosa.

Drizzle 1/4 teaspoon of ghee around the vella dosa and cook on low heat until well done. Flip over to cook the other side for a few seconds and serve warm.

Serve Vellai Dosa as a delicious dish during Navratri or as breakfast along with Peanut Chutney.
