Menestra de Verduras Riojana

The dish belongs to the huerta of the Ebro valley, the irrigated vegetable plains around Calahorra whose Roman name, Calagurris, gives the local adjective calagurritana still used for the city's produce. Spring is the season, when artichokes, peas, broad beans, and white asparagus come in together. It is a long-standing restaurant and household specialty of the area; the Calahorra restaurant Casa Mateo has served its menestra for close to a century, since 1929.

A plateful of distinct vegetables, each still itself: artichoke hearts gone meltingly soft, asparagus tender but whole, peas and broad beans sweet and bright green, all gilded with a thin, glossy sauce. The salty depth of jamon runs under the clean, faintly bitter green flavors. Eaten warm, never piping hot, so each vegetable's own taste stays distinct rather than blurring into a single stew.

The method is the opposite of a one-pot stew: each vegetable is blanched or cooked separately to its own ideal point, because artichokes, asparagus, peas, and beans soften at very different rates and a single pot would leave some mush and some raw. Artichokes are held in acidulated water so the cut surfaces do not brown through enzymatic oxidation. They are then folded together into a base of onion and diced jamon sweated in olive oil, with a spoonful of flour cooked in to make a light sauce that lightly coats and binds rather than drowns; a little of the vegetable cooking water loosens it.
