Lean, fine and mountain-scented, the loin of the Corsican cured trio.

Overview

Lonzo de Corse, or Lonzu, is the protected Corsican loin cure. The lean loin is salted, peppered, cased and matured with a strip of fat left along one side, creating a cleaner, less marbled slice than Coppa de Corse while retaining the island's Nustrale pig character.

Where it's from

Corsica (regional), Corsica, France

Climate. The Corsican mountains, where island pigs range on chestnuts and acorns.

How to recognise it

The whole piece is compact and cylindrical, cased and tied, with a lean red slice bordered by a deliberate white fat strip. Pepper is clear and smoke is not dominant. Excessive dryness, grey centre meat, rancid edge fat or air beneath the casing are faults.

Origins and history

Corsican winter slaughter divided the pig according to muscle, fat and time. The loin was lean and valuable, so families cured it as a compact whole piece that could mature faster than a ham. A protective fat strip helped prevent excessive drying, while pepper and casing guarded the surface. The Nustrale pig's outdoor life among chestnut, oak and maquis gave even this lean cut a distinctive aroma. During the twentieth century imported pork and generic lonzo threatened the island identity. Breed recovery and producer organisation led to AOC and then European PDO protection in 2014. Lonzo de Corse therefore remains legally separate from the newer Île de Beauté PGI products introduced for a broader Corsican charcuterie chain.

Serving and cultural significance

Slice thinly and serve before fattier coppa or prisuttu on a Corsican charcuterie board. Pair with bread, brocciu, figs, chestnuts and light red wine. It can also be laid over warm bread or polenta so the protective fat strip softens without cooking the lean.

Recipe and cure

Traditional or protected production

The AOP uses qualifying Corsican-breed loin, protected husbandry and processing in Corsica. The muscle is trimmed with its characteristic fat cover, salted, peppered, cased and matured. It is not the same legal product as Lonzo de l'Île de Beauté PGI.

Sea salt and black pepper, salt-box method; no fixed percentage.

Method

  1. Salt and season the cut by the traditional method and rest cold so the salt draws through.
  2. Wash or brush off surface salt and begin the slow dry.
  3. Case or hang as the style requires.
  4. Age to the target loss, judging by weight.

Notes

  • The official protected specification controls the named product. Any Curesmith EQ, starter-culture, curing-salt or home-scale adaptation is a separate method and must not be presented as designation-compliant.
  • A more efficient way of curing this product is using the EQ Method. No more than 2.5% salt to meat weight is required. To follow the EQ method, please use our whole-muscle EQ curing calculator to work out proper ratios and curing times.
