In a mixie coarsely pulse the ginger, garlic(if adding), fennel seeds, and curry leaves.
Chop the mint leaves.
In a wide bowl add the besan, rice flour, chopped mint leaves, pulsed ginger mixture, red chili powder, salt, and cashew nuts.
Do not roast the the cashew nuts. Add raw cashew nuts. Add whole cashews.
Heat the 2 tsp of oil and add it to the flour mixture.
Mix everything and sprinkle a little water.
Make a stiff dough.
Heat oil for deep frying.
When it becomes hot, bring the flame to medium.
Take the cashew pakoda dough in small portions and carefully put them into oil.
Deep fry in oil till it becomes crispy golden brown.
Fry on both sides.
Take it out once the oil sound subsides.
Drain in a kitchen towel.
Repeat this for the rest of the cashew mixture.
This pakoda can be stored in an airtight container for 2 days.
Allow this to cool completely and then store it in a box.
It will stay crispy for 2 days. But trust me it is highly addictive. So it won't stay long.
