I was distinctly unimpressed by my first ever sip of true, authentic Indian chai. In fact, I’d say my reaction bordered on revulsion. As someone whose journey in tea drinking had progressed from milky teenage cups of builder’s tea, through to Earl Grey with a slice of lemon, through to all sorts of exotic, loose leaf brews from the corner of the globe drunk strictly unadulterated – heaven forbid milk or sugar should make it anywhere near the teapot – I was unprepared for the assault on my tastebuds mounted by my first real chai, sipped in the ferocious sun atop a roof terrace in Delhi.
