Agnello al Forno con le Patate Pugliese
Puglia's simplest and most Sunday lamb preparation: bone-in lamb shoulder or leg roasted directly on a bed of sliced potatoes, onion, and cherry tomatoes, with olive oil, white wine, and fresh rosemary. The lamb fat renders during roasting and bastes the potatoes from above; the tomato and onion provide moisture and sweetness at the pan base. The potatoes at the bottom absorb all the lamb dripping and become lacquered, soft inside and caramelised underneath. No further sauce is made — the pan juices are poured over at service.

The Method
1
Heat the oven to 180 °C. Score the lamb deeply at the joints. Into each score, press a sliver of garlic and a short sprig of rosemary. Season the lamb surface with salt and pepper.
2
Lay the sliced onion across the base of a large roasting pan in an even layer. Arrange the sliced potatoes over the onion, overlapping slightly. Season the potato layer separately with salt, pepper, and a generous drizzle of olive oil — the potatoes require their own seasoning, not only the dripping that will fall from above. Scatter the whole cherry tomatoes and remaining garlic cloves among the potatoes. Pour the white wine over the base. The base should be moist and glistening; if the wine appears insufficient to cover the pan floor, the base will dry out and burn during roasting.
3
Set the lamb directly on top of the vegetables — it must rest on the potato and tomato bed, not on a rack. Drizzle the remaining olive oil over the lamb so the surface is visibly glistening. This is where the dish lives or dies: the lamb fat and olive oil will render and baste the potatoes continuously from above; if the lamb is elevated away from the vegetables or the pan is covered, neither the caramelisation of the potato surface nor the crisping of the lamb skin can occur.
4
Roast uncovered at 180 °C for 1 hour 30 minutes. Do not cover the pan at any point. After 1 hour 30 minutes, raise the oven to 200 °C and roast for a further 30 minutes. The lamb skin should be deeply coloured and beginning to pull back from the bone; the potato edges visible above the lamb should show bronze caramelisation.
5
Remove the pan from the oven. Rest the lamb, uncovered, for 15 minutes in the pan. During this time the juices redistribute and the potato layer continues to caramelise in the residual heat of the pan. The underside of the potato base, when lifted at the edge with a spoon, should be lacquered and dark gold.
6
Transfer the lamb to a board and carve. Serve the potato and vegetable base directly from the pan. Pour the collected pan juices over the carved lamb and potatoes at the table. No separate sauce is made.

Quality Hierarchy
01
Reserve — Milk-fed lamb from a named Puglian or southern-Italian producer, Sieglinde or Agata waxy potatoes, first cold-press Puglian DOP olive oil, hand-picked cherry tomatoes on the vine. Every element at peak season.
02
Estate — Bone-in lamb shoulder from a known local butcher, Desiree or Charlotte potatoes, a good extra-virgin olive oil, ripe sweet cherry tomatoes. Rosemary cut fresh the day of cooking.
03
Market — Supermarket bone-in lamb shoulder or leg, Charlotte or similar waxy-variety potatoes, standard supermarket extra-virgin olive oil. Cherry tomatoes from a punnet. Acceptable Sunday result.
04
House — Any bone-in lamb cut available, waxy potatoes of any named variety (avoid floury types that will disintegrate), standard olive oil. The technique matters more than the sourcing at this rung — do not cover the pan.

Sensory Tests
◇Sight. Lamb skin is deeply coloured and pulling back from the bone after the final 30 minutes at 200 °C.
◇Sight. Potato edges visible above the lamb show bronze caramelisation; the base of the potato layer, when lifted at the edge, is lacquered dark gold.
◇Smell. The kitchen carries a clean scent of rendered lamb fat, rosemary, and sweet reduced tomato — no raw or steamed smell.
◇Touch. The potato slices yield immediately to the tip of a knife but hold their shape; they do not fall apart when lifted.
◇Where it lives or dies. The lamb must rest directly on the uncovered vegetable bed throughout roasting — covering the pan or elevating the meat destroys both the caramelisation of the potatoes and the crisping of the lamb skin, and the basting action that defines the dish cannot occur.
