Kaju Katli

Kaju Katli is part of the broad barfi family of dense, sliced milk-and-nut sweets long made by India's halwai (confectioner) tradition; the cashew, introduced to India by Portuguese traders in the 16th century, gave rise to the all-cashew version that displaced milk with ground nut. Its precise inventor is unrecorded, and the popular royal-kitchen tales — a Maratha cook said to have swapped almonds for cashews in a Persian-style sweet, or a Mughal chef said to have cut it diamond-shaped after the Kohinoor — are folk attributions rather than documented history. What is clear is that it became, and remains, the default Indian festival and gifting mithai, sold by weight at sweet shops across the country.

A smooth, matte-to-glossy diamond, pale ivory, sometimes mirror-bright under a leaf of silver. It is firm enough to lift cleanly yet soft enough to cut with the side of a fork, and it melts on the tongue into a fine, slightly grainy paste with no chew. The flavour is pure roasted cashew, buttery and mildly sweet, lifted by a faint warmth of cardamom; the silver leaf is tasteless. It is eaten at room temperature, a piece or two at a time.

Everything turns on sugar-syrup chemistry and the cashew's own fat. Sugar is boiled with water to a one-string consistency — a single thread that forms when a drop is pulled between finger and thumb, around 110–115°C — at which point the syrup holds just enough moisture to bind the nut without crystallizing hard. Finely ground cashew is folded in off the heat and cooked briefly; the nut's high oil content keeps the mass pliable and, with brief kneading, smooth and glossy rather than gritty. Overcooking the syrup or the dough drives off too much water and the slab turns dry and crumbly; underdone, it stays sticky and won't hold a cut. The warm dough is rolled thin between sheets and cut while still soft; it sets firm as it cools and the sugar stabilizes.
