Soak large Lemon Size Tamarind Ball in 3/4 cup hot water for 15 minutes.
Squeeze and collect the thick extract (around 1.5 cups) and keep aside.
Soak Groundnuts in water for 10 minutes. Drain and keep aside.
Heat a pan, add 1/2 cup sesame oil (more oil is used for long shelf life).
Add mustard seeds, chana dal and whole red chilies. Once mustard crackles, add the thick tamarind extract and soaked groundnuts.
Next add turmeric powder, hing or asafoetida and red chilli powder.
Mix well and allow it to simmer on low flame until it thickens. Cook this until there is no raw tamarind smell.
Add jaggery, salt to taste and mix well.
Next add the podi and you will notice the pulikachal consistency to thicken. Switch off heat, remove the pan from heat and allow it to cool completely.
