In a big bowl, add the jaggery and water, mix till all the jaggery dissolves (can microwave for 1 or 2 min. to dissolve). Filter and discard the impurities. To the jaggery water, add spoon by spoon whole wheat flour and mix thoroughly without any lumps.
Add the crushed or powdered cardamom and mix. The consistency of the batter should be like that of idli batter - not too thick nor too thin. The batter should be like that shown in this picture.
In a pan, heat enough oil and keep in a medium flame. Once the oil is hot enough, add approximately a tablespoon of the batter and fry. Flip and fry till both the sides are nicely golden brown in color.
Scoop it out of the oil, drain the excess oil.
Serve warm or at room temperature. Store in an airtight container.
