This recipe for traditional Latin blood sausage is fairly mild. Despite its dramatic looks and deep color, it is reminiscent of high-quality bologna. It's salty like most sausages, and the clove-infused sofrito adds some backbone and depth. Texturally, the rice gives it body, and the chunks of pork add some pleasantly chewy bits. Pork blood is available from some butchers, but is more widely-available at Asian or Latin markets.
