See how fine the urad dal powder is,Set aside. To a pan add palm jaggery add 1/4 cup water to it.Heat it up to melt.
Just heat it up for the jaggery to dissolve completely.(no syrup consistency needs to be checked).SWITCH OFF.Strain it to a kadai.
Add 1 cup water.Now add urad dal powder to it.
Use a whisk to whisk well, should be free from lumps.If this mixture had lumps then while stirring it will be lumpy so make sure to mix very well, use your hands if needed.Now keep the kadai on the stove.Use a wooden laddle, we use a 'thuduppu' for kali.
Add 1 tbsp oil, while drizzling drizzle it from the sides so that sticking will be less at the sides too.Keep mixing.When it starts to stick add remaining 1/2 tbsp oil and keep cooking. It will roll like a ball.
