Sohan

Sohan is a specialty of Qom, the Shi'a shrine city south of Tehran, and its modern form is dated to the late Qajar period, around the 1910s. A local account credits a confectioner, Mollah Ibrahim Shammai, who presented a new halva-like sweet to a court official; the man remarked that it had worked like a sohan — a file — on his stomach and helped his digestion, and the name stuck. The Austrian traveler Alfons Gabriel, crossing the Iranian deserts in the early twentieth century, recorded sohan-e Qom as a renowned flour-sugar-butter-and-pistachio confection sent to the farthest cities of Iran. Its making passed down through Qom families and became a defining craft of the city.

A thin golden shard that snaps clean and then dissolves to a buttery, brittle crunch on the tongue. Sweet first, with a toasted, almost caramel depth from the cooked flour and butter, and a faint bitter edge that saffron and a touch of scorch give it. Cardamom and rosewater hum underneath. Slivered pistachios and almonds stud the surface for a nutty break. It is rich enough that one or two pieces with bitter tea is the measure.

Sohan is a caramel brittle built on a flour roux. Wheat sprout extract and flour are cooked slowly in butter so the starches toast and brown, then sugar (and sometimes honey) is dissolved in and boiled to the hard-crack stage, the temperature that sets a clear, snapping sheet rather than a chewy toffee. Saffron, cardamom and rosewater go in late, off the worst of the heat, so their volatile aromatics survive. The molten sheet is spooned into thin rounds onto a cool surface, scattered with nuts, and left to set glassy. Pull the syrup short of hard-crack and it stays sticky; cook it too far and it tastes burnt.
