Daube Gasconne à l'Armagnac

Ingredients

• 1.2 kg paleron or joue de bœuf (beef cheeks preferred), cut into 150 g pieces
• For the marinade
• 750 ml Madiran wine, young and tannic; one full bottle
• 100 ml Armagnac
• 2 medium carrots, diced
• 2 medium onions, diced
• 4 cloves garlic
• 1 bouquet garni
• 6 juniper berries
• 1 orange zest, in strips
• 1 tsp black peppercorns, whole
• For the braise
• 60 g goose fat, for searing
• 250 g pruneaux d'Agen, pitted
• For the lut (flour-paste seal)
• 150 g plain flour, mixed with enough water to form a stiff dough
• 60 ml water, approximately, to bind the lut dough

Method

1. 1
   Place the beef pieces in a deep non-reactive bowl. Pour over the Madiran and Armagnac. Add the diced carrots, diced onions, garlic, bouquet garni, juniper berries, orange zest strips, and black peppercorns. Cover and refrigerate for 24 hours. The meat is ready when it has taken on the deep purple of the wine throughout its surface.
2. 2
   Lift the meat from the marinade and dry each piece thoroughly with a cloth. Strain the marinade and reserve the liquid and the solids separately. Pour the strained liquid into a wide saucepan and reduce over high heat by one third. The reduction is done when the liquid has darkened perceptibly and its aroma has shifted from raw wine to something closer to a concentrated stock.
3. 3
   Heat the goose fat in a heavy pan over the highest heat the fat will sustain without burning. Sear the dried beef pieces in batches, turning once, until each surface has formed a deep, almost black crust. This step decides the dish: a timid sear produces a grey, insipid sauce, while a proper crust — nearly carbonised at its edges — provides the bitter, caramelised backbone the Armagnac and prunes will build against. The crust is formed when the surface no longer yields to pressure and releases cleanly from the pan.
4. 4
   Preheat the oven to 120 °C. In the earthenware daubière, layer the seared beef, the reserved strained aromatics from the marinade, and the pitted pruneaux d'Agen. Pour the reduced marinade over the assembly. Mix the flour and water into a stiff dough and press it in a rope along the join between the daubière and its lid, sealing completely. The seal is sound when no steam can escape at the join.
5. 5
   Set the sealed daubière in the oven at 120 °C and cook for 4 to 5 hours without disturbance. The lut must remain intact throughout; any cracking indicates a loss of the trapped steam that defines the cooking environment. After 4 hours, listen for the faintest murmur of movement within the vessel — the sign that the braise is working at the correct temperature.
6. 6
   Break the lut seal at the table or just before service. The sauce should be dark, slightly sweet, and dense enough to coat a spoon; the prunes will have partially dissolved into the gravy. Serve with fresh tagliatelles or a pommes purée enriched with goose fat. The daube improves over 3 days as the gelatin sets and the flavours meld; taste on reheating and adjust seasoning accordingly.
