Halvas Farsalon (Χαλβάς Φαρσάλων), Farsala's Thessalian Halva

Halvas Farsalon belongs to Farsala in Thessaly, and it is not the semolina halva spooned from a pot, and not the sesame block from the grocer. It is a glossy, caramel-brown slab of niseste, starch, sugar, oil, and almonds, cut into heavy squares with a scorched top that grips the knife a little.

The whole dish rests on one stubborn instruction: keep cooking after it thickens. At first it looks finished too early, pale and stiff and rather disappointing. Then, with steady stirring, it darkens, turns shiny, and begins to pull from the pan in slow folds. That browning is the dish. Farsala's color comes from the pan, not from cinnamon, cocoa, or any little trick slipped in at the end.

I leave it plain because Farsala leaves it plain. A little sugar on top goes under strong heat until it blisters dark, and then the halva rests until it can be cut cleanly. Your first tray may not look like a halvadopoios made it at the fair, but it will taste of the real thing: sugar, starch, almonds, patience.
