As it warms up, add the oil. You can use groundnut oil also.
First add the tamarind and garlic, roast it for 1 min on low-medium flame.
Now add the chillies and sesame seeds to this. Roast for 1 more minute until you start getting a light aroma of roasted sesame and the heat of the chillies.
Turn off the gas and allow this to cool for few minutes.
Now take the medium mixie jar and coarsely grind the roasted peanuts. Keep this aside.
Using the whipper mode, grind the other ingredients in short bursts. You will get a coarse mixture.
Add in the powdered groundnuts and salt (as per taste).
Give it 1-2 short blitzes in the mixer and you are done.
Allow this to cool and store it in an air tight container. Finish it within 1-15 months.
