Turkish Delight (Lokum) — The Cornstarch Gel and the Water That Matters
Lokum (لقوم — thought to derive from the Turkish rahat ül-hulküm, "comfort of the throat") has been made in Istanbul since at least the eighteenth century, when the confectioner Hacı Bekir arrived from Anatolia and established the shop near the Grand Bazaar that still operates today under his name. The preparation was brought to Britain in the early nineteenth century, where it was renamed "Turkish Delight" — a name that, through C.S. Lewis's use of it in The Lion, the Witch and the Wardrobe (1950), gave it a permanent place in the Western literary imagination as the food of seduction and betrayal. Edmund Pevensie's capitulation to the White Witch over a box of Turkish delight is one of confectionery's most famous cultural appearances.
Lokum is a cornstarch gel — one of the only confections in the world built on cornstarch as the primary structural agent rather than gelatin, agar, or pectin. The technique: water, sugar, and cornstarch are combined (cornstarch first dispersed in cold water to prevent lumping) and cooked at low heat with constant stirring until the mixture clears from white to translucent and begins to pull away from the sides of the pan. This cooking takes 45–60 minutes for a standard batch — significantly longer than any other cooked confection. The patience is the technique. During this time, the starch granules fully gelatinise, excess water evaporates, and the mixture develops from a thin starch-water suspension to a thick, elastic, translucent gel. Flavourings (rose water, mastic, bergamot, pomegranate) are added off the heat. The gel is poured into a cornstarch-dusted tray, allowed to set (12–24 hours), cut, and rolled in icing sugar mixed with cornstarch to prevent adhesion.
