Magret de canard séché

Deep red duck breast rimmed with fat, salt-cured and air-dried, sliced thin.

Draft

This recipe is a draft, pending verification by The Curesmith. Treat the salt, cure and timing figures as provisional and confirm them against your own judgement before curing.

Introduction

Magret de canard séché is deep red duck breast rimmed with fat, salt-cured and air-dried, sliced thin. Deep red duck breast beneath a clean white fat cap, sliced thinly. The meat should be firm but not hard, and the fat should smell sweet and fresh. The Codex treats the product as a complete curing or cooking system, not simply a famous name. Raw material, cut or particle size, casing, smoke, fermentation, heat treatment and maturation all contribute to the result. The current legal or quality status is Generic French speciality : no EU GI. The source tradition and the Curesmith home method are kept separate.

The Curesmith home method

The encyclopedia article is ready, but the Curesmith home recipe is withheld pending product-specific technical validation of its safety endpoints. No formula or process should be inferred from the traditional description.

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.

Nitrite is optional for a whole muscle: it develops the cured colour and rounds the flavour, but the safety comes from the salt and the weight loss, not the nitrite. If you cure without it the meat will be a darker red-brown, which is safe and traditional.

Method

1
Weigh and prepare the meat. Weigh the trimmed muscle accurately and pat it dry. Every cure amount is calculated from this weight.
2
Measure and mix the cure. Weigh the salt, cure and dextrose precisely, then combine with the crushed aromatics into an even rub. If you are curing with no nitrite, simply leave the cure out.
3
Apply the cure and bag. Rub the cure evenly over all surfaces, pressing it in, then vacuum-seal, or bag it in a large enough bag with the air pressed out.
4
Cure in the refrigerator. Refrigerate at 2 to 4 C (36 to 39 F) for the calculated time, turning every couple of days. Equilibrium curing cannot over-salt, so a few extra days do no harm.
5
Rinse and dry. Once cured, rinse off the surface cure and pat dry. Weigh the meat and record the green weight, then hang at 12 to 15 C (54 to 59 F) and 70 to 82% RH.
6
Hang to dry. Hang the piece at 12 to 15 C (54 to 59 F) and 70 to 82% RH so it dries evenly. This one is not cased: none.
7
Mature to weight loss. Continue to hang and weigh regularly. It is ready at 38% weight loss, measured against the recorded green weight, and gated on weight, not the calendar.
Key tipsTwo methods are offered. The EQ (equilibrium) tab is the modern, precise version: measured salt, bagged, timed by thickness. The Box (traditional) tab is the salt-box method, salting by weight. Nitrite is optional here and only adds colour and flavour. Both reach the same safe finish, gated on weight loss.
ImportantThis is eaten uncooked, so it is safe only once it has reached at least 38% weight loss, measured against the recorded green weight. Never eat it before that.
