Morcilla de cebolla

An onion-rich blood sausage.

Introduction

Morcilla de Cebolla is the onion-led branch of Spanish blood sausage. Cooked, well-drained onion forms most of the filling, with pig blood and pork fat supplying colour, richness and bind. It is poached and usually cooked again before serving.

Purpose and scope

The recipes published on The Curesmith are intended for educational and informational purposes only. Meat curing, fermentation and smoking involve processes that, if carried out incorrectly, can result in products that are unsafe to eat. By using any recipe on this website you acknowledge that you do so entirely at your own risk, and you agree that The Curesmith and its authors cannot be held liable for any outcome arising from its use.

Limitation of liability

The Curesmith and its authors accept no responsibility or liability for any illness, injury, loss or damage arising from the use of these recipes, including but not limited to illness caused by improperly cured, handled or cooked meat products, errors in measurement or technique, equipment failure, or deviation from the stated method or quantities.

Nitrite and cure safety

Meat curing involves the use of nitrite salts, which must be measured accurately and used strictly according to the quantities specified. Nitrite in excessive quantities is toxic. Please ensure you understand the following before proceeding:

  • Always use a calibrated digital scale accurate to at least one gram. For smaller batches, a scale accurate to 0.1g is strongly recommended.
  • Never exceed the stated cure amounts. Never substitute cure types without recalculating.
  • Store all curing salts clearly labelled, separately from regular salt, and out of reach of children.
  • Different cure products have different nitrite concentrations. Always check your manufacturer's label and adjust quantities accordingly.

Food hygiene and cross-contamination

Raw and cured meat products must be stored, handled and prepared in a clean environment using food-safe equipment. Hands, surfaces, tools and containers must be thoroughly cleaned and where appropriate sanitised before use. Cross-contamination between raw meat and ready-to-eat products must be avoided at all times.

Temperature control

Temperature control is critical throughout all curing and smoking processes. Inadequate temperature management can allow the growth of dangerous pathogens including Clostridium botulinum, Listeria monocytogenes, Salmonella and E. coli. A reliable refrigerator thermometer and a calibrated probe thermometer are essential pieces of equipment for anyone producing cured or smoked meat at home.

Uncooked cured products

Whole muscle products that are eaten without cooking, such as air-dried bresaola, coppa or prosciutto, must reach their target weight loss before consumption. Products that have not been cured and dried to the correct specification may not be safe to eat uncooked. Pancetta and guanciale cured to less than 38% weight loss must not be consumed uncooked.

Bacon and other uncooked cured products

Bacon and other uncooked cured products must be cooked thoroughly before eating. Cold smoking adds flavour and colour but does not cook the product. A cold-smoked bacon or sausage remains a raw product and must reach a safe internal temperature before it is safe to consume. For pork and beef this is 72°C / 162°F. For poultry this is 74°C / 165°F.

When in doubt, seek professional guidance

If you are unsure about any aspect of the curing, smoking or fermentation process, we strongly encourage you to seek formal training or guidance from a qualified food safety professional before proceeding. The information on this website is not a substitute for proper food safety education and training.

Commercial production

These recipes are produced for home and small-scale producers. They are not intended for commercial food production. Commercial meat processing is subject to regulatory requirements that vary by country and jurisdiction. If you intend to produce cured or smoked products for sale, you must ensure full compliance with all applicable food safety regulations in your region.

Method

1
Cook the onions. Dice the onions and simmer them in lightly salted water for 30 to 45 minutes, then drain and let them cool. Raw onion reduces a great deal in cooking, so expect roughly five parts raw to yield one part cooked.
2
Dice the fat. Cut the pork back fat or lard into small, even cubes by hand rather than grinding it.
3
Mix the paste. Combine the diced fat, cooked onions, blood and spices, folding everything together into an even mixture.
4
Stuff the casings. Fill the mixture into pork or beef casings of 36 to 40 mm.
5
Poach the sausages. Lower the sausages into hot water and cook them at 80 C (176 F) for about 45 minutes. Hold the water at 80 C (176 F) rather than letting it reach a rolling boil, which would split the casings.
6
Chill and store. Immerse the cooked sausages in cold water for 10 minutes, then cool them in air and refrigerate. There is no drying stage.
Key tipsThis is the house version of a cooked product; the Atlas entry carries the traditional detail. Keep everything cold, cook to a measured core temperature, and cool quickly.
ImportantThis is a cooked product. Cook thoroughly to a safe internal temperature of 72 C / 162 F before eating, cool promptly and keep refrigerated.
