What are pinchos (sometimes spelled “pintxos”)? They’re the tapas of northern Spain, small snacks similar to hors d’oeuvres, often layered and skewered with a toothpick. Sketches of Spain, in Oak Cliff’s Bishop Arts neighborhood, is introducing Dallasites to myriad combinations of such regional flavors as morcilla (blood sausage), smoky Spanish chorizo, piquillo peppers, and boquerones (marinated white anchovies). Each pincho is built to be one big bite or, more practically, two small ones. Sample choices at the bar, where platters of tempting options are set out for inspection (though not, as in Spain, uncovered). We devoured the croquetas stuffed with ibérico ham and bechamel; layers of goat cheese, membrillo, and walnut also proved an unexpected pleasure. For a home-style dessert, try the torrija, bread soaked in milk, fried, and sprinkled with cinnamon. All wines are Spanish, and affordable half glasses make pairings fun.
