A Bocadillo de Morcilla de Burgos succeeds or fails on the sausage inside it, so it is worth understanding what morcilla de Burgos actually is before assembling one. It is a rice-based blood sausage: cooked rice, blood, pork fat, and onion packed into a casing and simmered, with a seasoning that runs smoky and savory rather than sweet or heavily spiced. The rice is what sets it apart from onion-bound or sweet regional blood sausages, and it is why this sausage, and the bocadillo built on it, behaves the way it does under heat.
That rice base dictates the build. Because the interior is loose grains held by fat and blood, the morcilla has to be cut into substantial rounds, on the order of a finger's width, so a slice survives being lifted and bitten. Those rounds go onto a hot plancha and are left long enough to build a real crust; the smoky seasoning deepens with the sear, and the cut faces of rice firm up at the edges. The seared slices are packed into a split barra or crusty roll. Done well, the contrast is the whole pleasure: a dark, savory, almost crackling exterior against a rich, soft, faintly smoky interior, with the rice reading as texture. Done badly, an under-seared sausage stays gluey and the rice slumps into a wet heap the moment the bread is squeezed, and the bread soaks through with fat.
Because the flavor already runs rich and smoky, additions stay minimal and exist mainly to lighten it. Sweet fried green peppers are the standard foil, their mild bitterness and soft give balancing the dense, iron-tinged sausage. A little caramelized onion echoes the onion already in the mix without fighting it. Beyond that, the rice-bound Burgos style is best left to speak for itself. Other Spanish blood sausages, such as the sweeter cinnamon-and-pine-nut styles of other regions, make genuinely different sandwiches and each deserves its own article rather than being crowded in here. For this one, the rule reduces to two things: a true Burgos rice morcilla, and enough heat under it to crisp the cut.
