Dry-Cured Chorizo

This is the keeping version of my chorizo: fermented, cold smoked and then dried until it has lost 40 percent of its weight. It takes patience and a little more care than the cold smoked one, but a well-made dry chorizo hanging in the larder is one of the real rewards of curing.

Introduction

Fermentation is the heart of it. The starter culture drops the pH and sets the sausage on a safe path, and only once it has fermented does it take the smoke and go to dry. Weigh it against its green weight and do not eat it until it has reached at least 38 percent loss. As with all my sausages, get the seasoning right with a taste test before the cure and culture go in.

Where it comes from

Pork cut chart with the Shoulder highlighted
Pork · ShoulderThis dry-cured chorizo is built on pork shoulder, whose fat is essential to a fermented sausage: it carries the flavour and keeps the texture right as the sausage dries.

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
Keep everything cold. Chill the pork, and your grinder parts, until ice-cold, then grind through a 6 mm plate into a bowl set over ice.
2
Mix the seasoning (no cure or culture yet). Dissolve the milk powder in the ice water. Mix the salt, dextrose, paprika, ancho, cumin, white pepper and onion powder through the meat with the milk-water until even and tacky. Hold back the Cure #2 and the starter for now.
3
Taste test, before the cure. Poach a small ball of the seasoned farce, cool it, and taste. Adjust the seasoning now, before the Cure #2 and starter go in. Never cure and then fry a test straight away.
4
Add the cure and culture. Once the seasoning is right, work the Cure #2 through the farce, then mix in the dissolved starter culture. Mix for at least another minute so both are evenly spread.
5
Stuff the casings. Stuff into hog casings firmly, avoiding air pockets, and prick any you see with a sterile pin. Record the green (pre-drying) weight so you can track weight loss later.
6
Ferment to pH 5.2. Hang at 20 to 24 C (68 to 75 F) and 85 to 90% humidity for 2 to 4 days. Confirm pH 5.2 with a calibrated meter before moving on. Do not rely on colour strips.
7
Cold smoke below 25 C. Cold smoke below 25 C (77 F), never above, about 4 hours with a medium smoke, or over several shorter sessions. Smoke at night if the day is warm.
8
Dry to 40% weight loss. Hang in a drying chamber at 12 to 14 C (54 to 57 F) and 72 to 75% humidity. Weigh weekly against the recorded green weight. The chorizo is ready when it has lost 40% of its weight.
Smoking guidanceAfter fermentation and before drying, cold smoke below 25 C (77 F), the same way as the cold smoked chorizo: about 4 hours with a medium smoke, or over several shorter sessions for a deeper flavour. Smoke at night if the day is warm.
Key tipsThe taste test comes before the cure and culture, always. Confirm pH 5.2 with a meter before smoking, and hold the smoke below 25 C (77 F). Do not eat it until it has reached at least 38% weight loss (40% recommended), measured against the recorded green weight.
ImportantDry-cured chorizo is eaten uncooked and is safe only once it has reached at least 38% weight loss (40% recommended). Never taste or eat it before the minimum weight loss is confirmed by weighing against the recorded green weight.
