Casa Ortega's onion blood sausage is a 500-gram artisanal product made without preservatives. This sausage is vacuum-packed to ensure freshness and quality and is ready to consume or keep refrigerated. It is recommended to unmold it 30 minutes before consumption to appreciate its full flavor, similar to freshly cut product. Preparation process: the onion is finely chopped and sometimes fried in lard, then mixed with hot pig's blood before being stuffed into casings. The product is boiled to harden the tissues and prevent fermentation. The blood sausage is creamy and fluid, perfect for spreading on bread or adding to stews.
