Alur Chop
Alur chop (alu meaning potato, chop being a Bengali loan-word for a fried cutlet, inherited from the British "chop") is the workhorse of Bengali street snacks: every tea stall, every train platform, every late-afternoon adda has a stack of these warming under a glass cover. The construction is two layers. The inner mash is heavily seasoned: boiled potato folded through fried onion, ginger, green chilli, roasted cumin and a measured punch of Bengali bhaja moshla (a dry-roasted spice blend of cumin, coriander and dried chilli). Some versions add a few peanuts or roasted chana dal for crunch; in Kolkata the mash often includes a slick of mustard oil for fragrance. The outer shell is a thin chickpea-flour batter, the same family as beguni and piyaju, fried hot so it sets into a thin crisp casing rather than a heavy crust. The trick is contrast: a shell crisp enough to crackle, a centre soft and yielding and a touch wet from the onion. They are sold individually wrapped in newspaper for a few rupees and eaten standing up, often with muri puffed rice and a small dollop of kasundi (Bengali fermented mustard sauce) on the side. A monsoon and winter snack above all, when the cold air makes the hot oil and the inside-warm chop feel particularly right.
