Recently I experimented it:
I used my grinder to make a mix of of spices - everything corinadar seeds, cumin seeds, garam masala, haldi, lal mirch to make a very fresh mix and cooked my curry - it tasted awesome.
Similiary used everything fresh - tomatoes, ginger, garlic paste
Chicken (unfortunately you can not get it here fresh in the west as you can get it in Pakistan)!
