Chill the cocktail glass; prepare your garnishes and chop the roughly, actually you need kaffir lime leaf, instead of the lemon peel (can be found in an Asian store, and istead of the ginger try to find blue ginger or galangal. Now that you have your ingredients ready, muddle them in a stirring glass (like caipirinha) add ice all the way til the top and add the vodka, then add the coconut milk, the sugar syrup, the lime juice, shake well and serve in a cocktail glass, add chili powder on top, and a straw of lemongrass..it should have hints of the famous thai lime-coconut soup called thom kha gai....cheers
