Tiffin is as much a tastebud map as a cookbook, organised carefully with an extensive key defining ingredients, albeit with a rather non-inclusive bias for Hindi (and its speakers, as evinced by the &lsquobasic&rsquo recipes that include a very specific garam masala while pretending it is universal&mdashaggravating to regional cooks and misleading to foreigners). Within, the maps unfold by region&mdashWest, East, North, South, Central, and, for once acknowledging and celebrating the difference, Northeast India separately. Each region is zoned further into recipes for appetisers, poultry (and eggs), meat (and pork, making it a strange/ sensitive accessory), fish and seafood, &lsquovegetarian&rsquo (a regrettable demarcation of boundaries that creates a very distinct bias from &lsquovegetables&rsquo and relegates too many regional favourites to a no-cook&rsquos land), rice and breads, desserts and accompaniments (salads, preserves, sherbets). Each region has an overview that is too brief for truth or clarity the prefacing pictures for each section are far more evocative and could have served as introduction enough with careful captioning.
