Riñón

Riñón or kidney is a piece of beef offal that’s a favorite of few. It needs a thorough cleaning before grilling, which includes removing fats and veins and soaking it in water, vinegar, or lemon juice. It can be grilled whole, without its membrane, sliced in half or into more pieces but always over high heat, so a crust forms on the outside. It is served with lemon slices and salt for sprinkling over.
