The first time I tried Kairi Panna - a Maharashtran drink made out of raw mangoes - which was bought from a store, I was left very disappointed. Later I was offered a glass of homemade panna at a dinner party and hoping for the best, I took it. It was much much much better. Now that I tried making it at home, I absolutely love it - so refreshing, simple, yet satisfying with a nice flavour of cardamon and sourness of raw mangoes. Knowing us, we just had to try making a cocktail out of it later at night ;o) So have it plain or with some vodka and fiery chillies - it's a perfect drink either way! You can make as much as you want of this and keep it refrigerated for up to a month.
Instead of red Kashmiri chilli powder, you can spice it up with ground balck pepper or roasted cumin powder, or have it plain.
