Aragón, the IGP-protected milk-and-cereal-fed lamb, and the Casa de Ganaderos's own lineage.

As tradition built it

Serves 4 . About 1 hour 45 minutes

Ingredients

An outline, not yet a recipe: the tradition's method with its ingredients named but not weighed. Quantities are being added from sources inside the tradition, lead dishes first.

Method

  1. Season the ternasco simply with salt, olive oil, rosemary and thyme, pushing garlic into small cuts in the flesh: "only the spices that caress it, never the ones that cover it."
  2. Roast slowly at around 150°C, traditionally in a wood-fired oven.
  3. Roast the potatoes, cut into thick rounds, alongside in the same fat and juices, working laurel and garlic oil into the tray.

What a modern chef changes

Sous vide leg and confit potatoes

Method

  1. Sous vide the leg at a controlled 58°C for several hours before finishing, guaranteeing the pale pink doneness the IGP specification describes edge to edge.
  2. Finish hard in a Big Green Egg for genuine roasted colour and aroma without gambling that colour against overcooking.
  3. Confit the potatoes in the rendered lamb fat at a controlled low temperature rather than roasting them raw alongside from the start, giving a creamier interior before their final high-heat crisping.
  4. Blitz the pan juices, garlic and herb oil together in a high-power blender into an emulsified sauce rather than serving the juices plain.
