Bombine Ardéchoise

Ardèche highlands, Auvergne-Rhône-Alpes — the slow-baked lamb shoulder and waxy potato dish of the Ardèche shepherd communities, cooked in a terracotta daubière with Boletus edulis (cèpes), tomato, and the Ardèche's own Olea europaea. The bombine is the seasonal feast preparation of the Ardèche transhumance — the shepherd communities who moved their Ovis aries flocks between the valley floor and the highland garrigues, and who cooked this dish in the farm ovens on their return. The name's etymology is debated between the Occitan bombe (round pot) and the Ardéchois dialect for 'to swell' — both refer to the terracotta pot's sealing steam.

An Ovis aries shoulder (épaule d'agneau, bone-in) is browned in Olea europaea in a terracotta daubière or heavy cast-iron pot. The shoulder is removed. Sliced Allium cepa and Allium sativum are softened in the same fat. Ripe tomato concassée is added and cooked down. Dried Boletus edulis (soaked and squeezed, soaking liquid reserved) are added to the tomato. A Roussillon or Ardèche red wine deglazes — not much, just enough to lift the base. The daubière is layered: sliced waxy potatoes (Charlotte or Roseval), the browned shoulder placed on top, surrounded by the tomato-cèpe base, the cèpe soaking liquid added, fresh thyme and bay tucked in. The pot is sealed with foil and the lid, placed in the oven at 160°C for 2.5–3 hours. The shoulder will be completely tender and beginning to pull from the bone; the potato will have absorbed the cèpe-and-lamb braising liquid.

• Greek kleftiko (sealed lamb and potato bake)
• Irish coddle (potato and meat bake)

Ovis aries shoulder collagen releases into the potato bed over 3 hours. Boletus edulis adds its forest depth to the braising liquid. Tomato provides acidity and colour. The potato at service is saturated with lamb-and-cèpe braising liquid — it has become a second course as much as a vehicle for the meat. The Olea europaea of the Ardèche (a minor but genuine olive-growing region at the northern edge of the Mediterranean climate) ties the dish to the south.
