On the two-and-a-half hour drive from Kochi airport to Vengunad in the Palakkad region, my colleague, Sanjiv Valsan, veteran of many trips to God&rsquos Own Country, regales me with tales of his culinary experiences on Kerala&rsquos highways. It is noon by the time we hit the road, and Sanjiv declares that it&rsquos already too late for us to find toddy that&rsquos worth drinking. &ldquoYou have to have it by 9 o&rsquoclock latest, otherwise it gets disgustingly over-fermented and undrinkable,&rdquo he declares. Then he launches into mouth-watering descriptions of toddy shop fish curry and beef fry that he&rsquos had at humble roadside stalls. By now, we are ravenous, having caught our flight early that morning, without breakfast. Alas, there are no toddy shops on this stretch of the highway. Sanjiv&rsquos discourse on the delights of Kerala cuisine tails off when I remind him that we are here to write about Ayurvedic cuisine. &ldquoSo then,&rdquo he predicts grimly, &ldquowe&rsquore in for a diet of translucent vegetables.&rdquo
