Basic Lonza

Whole muscle recipeCuresmith Ratio

Basic Lonza

Lonza, or lonzino, is cured pork loin, and it is about as lean and clean as cured meat gets. Where coppa is rich and marbled, lonza is delicate: pale, tender slices with a gentle cure and a firm bite.

Introduction

This is a basic lonza, an equilibrium cure of salt, pink salt and a little pepper. Because the loin is lean it dries evenly and fairly quickly, which makes it a very good first whole muscle to try. Keep it in good moving air and take it to a proper weight loss before you slice.

Where it comes from

Pork · LoinLonza is cured from the pork loin, the long, lean muscle along the back. Its leanness gives the pale, delicate slices that set lonza apart from the richer whole muscles.

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
Weigh the green weight. Trim the pork loin of any ragged edges and weigh it accurately. Record this green weight: every cure amount, and your weight-loss target, is calculated from it.
2
Mix the cure. Weigh the salt, cure and any sugar precisely, then combine with the crushed aromatics into an even rub. Accuracy here is the whole recipe.
3
Apply the cure. Rub the mix over every surface, pressing it into any folds and the scored fat. Vacuum-seal, or use a zip-lock bag with all the air expelled.
4
Cure in the refrigerator. Refrigerate at 2 to 4 C (36 to 39 F) for the calculated time, turning the bag every 2 to 3 days and redistributing the liquid. With the equilibrium method you cannot over-salt, so a few extra days do no harm.
5
Equalise. Rinse briefly, pat dry, then reseal and rest in the refrigerator for the equalisation period so the salt distributes evenly right through the meat before drying.
6
Case and truss. After equalising, stuff the pork loin into a beef bung or a large collagen casing, pressing out air pockets, then truss tightly with butcher's twine so it holds its shape as it dries.
7
Air-dry. Hang in a curing chamber at 12 to 14 C (54 to 57 F) and 73 to 75% relative humidity, with gentle air movement and the pieces not touching. Record the hanging (post-cure) weight and weigh weekly from here.
8
Dry to the target weight loss. Gate on weight, not the calendar. The lonza is ready once it has lost the target percentage of its green weight. Firm throughout, with no soft spots.
Key tipsCured pork loin, sliced thin. A leaner alternative to coppa with a more delicate flavour. EQ curing is forgiving: a few extra days will not over-salt. Weigh weekly and let the weight-loss target, not the calendar, tell you when it is ready.
ImportantLonza is eaten uncooked and is safe only once it has reached at least 38% weight loss, confirmed by weighing against the recorded green weight. Never taste or eat it before the target is confirmed.
