lemons, preserved

Preserved lemons are made by packing fresh lemons in salt (with or without spices — cinnamon, cloves, bay, coriander seeds are traditional in Moroccan preparations) and allowing them to cure for at least 3 weeks, preferably a month. The salt draws out moisture (which combines with the natural lemon juice to create a brine), while lactic acid fermentation by naturally occurring bacteria transforms the lemon's chemistry — bitter limonin is reduced, and the rind softens to a silky, almost jammy texture. Only the rind is used in most applications: the flesh is discarded or used only in small amounts. The rind is rinsed, pith removed, and the remaining yellow skin is minced into a preparation. The flavor is intensely concentrated, aromatic, savory-salty, and complex — unlike fresh lemon in character, more like a condiment than a citrus. In Moroccan tagines, gremolatas, chimichurri, roast chicken marinades, grain salads (couscous, farro, quinoa), and pasta, preserved lemon adds background depth and aromatic complexity that fresh lemon cannot approximate.
