The Bocadillo de Papas Arrugadas takes one of the Canary Islands' signature plates and folds it into a barra. The papas themselves are small potatoes boiled in heavily salted water until the skins go taut and crackled and a dusting of salt clings to them, then dressed with mojo. As a sandwich filling this is unapologetically a starch-in-bread proposition, and the question that decides whether it works is entirely about the mojo: a thin, sharp green or red sauce doing the job a protein would do in any other bocadillo.
Build it in order and the logic is clear. The crust should be a plain, crusty roll with an open crumb, split and lightly oiled so the bread does not turn to paste under the wet potatoes. The papas go in whole or lightly crushed, never mashed smooth, because the point of the dish is the contrast between the salty skin and the soft interior, and a purée throws that away. The mojo is spooned over generously, pressed slightly so it soaks the lower crumb without pooling out the ends. Good execution keeps the potatoes warm or at room temperature, the salt crust still perceptible, and the mojo assertive enough to carry the whole thing: a mojo verde leaning on coriander and cumin, or a mojo rojo leaning on dried pepper and garlic. Sloppy execution shows up as under-salted potatoes, a timid mojo that disappears into the bread, or so much sauce that the barra collapses before the first bite is finished.
Variation is mostly a matter of which mojo and how much else is allowed in. The leanest version is potatoes and sauce and nothing else. Some builds add a sliced hard egg or a little soft cheese to give the filling something to push against, and a few push toward a fuller plate by adding stewed meat, at which point it shades into the broader stewed-filling bocadillo de guiso tradition that deserves its own article rather than being crowded in here. Across all of them the mojo is the load-bearing element: change its heat and acidity and you change the whole sandwich, far more than swapping the bread ever would.
