Tiella di Riso Patate e Cozze
Bari's signature baked one-dish — alternating layers of raw rice, sliced potatoes, and raw mussels in their shells in a terra cotta teglia (hence 'tiella'), with sliced tomatoes, onion, garlic, Pecorino, olive oil, and white wine, baked covered then uncovered until the potato is tender, the rice is cooked through by the mussel and vegetable liquids, and the top is golden. Unlike risotto, no stirring occurs — the rice cooks by absorption of the combined mussel-tomato-olive oil liquid from below. Served directly from the tiella at the table.

The Method
1
Heat the oven to 200 °C. Oil a terra cotta tiella or heavy earthenware baking dish thoroughly. Scatter the sliced onion and garlic across the base. Lay the potato slices in a single, overlapping layer — 3 mm is the maximum; thicker slices will not cook through in the time the rice requires. The potatoes are done at this stage when they form an unbroken, oil-glistening floor across the dish.
2
Open the raw mussels over a bowl, catching every drop of their liquor. Reserve the liquor. Discard any mussel that will not open under firm pressure. Distribute half the sliced tomatoes over the potato layer, then scatter the uncooked rice evenly across the tomatoes in a level layer. Drizzle half the olive oil over the rice. This is where the dish lives or dies: the rice must lie flat and even, with no gaps or mounds, so that it absorbs the rising mussel liquor uniformly during baking — uneven rice means uneven cooking, and no stirring will correct it.
3
Arrange the opened mussels, shell side down, across the rice layer in a single tier. Lay the remaining tomato slices over the mussels. Pour the reserved mussel liquor and the white wine evenly over the surface. Drizzle the remaining olive oil across the top. Scatter the grated Pecorino over everything in an even layer. The surface should appear thoroughly moistened but not pooled with excess liquid — the mussel liquor and tomato moisture are the only cooking medium; no broth is added.
4
Cover the dish tightly with foil or a lid and bake at 200 °C. After 30 minutes, remove the cover. The rice should have begun to swell and the liquid should be visibly reduced. Continue baking uncovered for a further 15–20 minutes. The dish is ready when the potato yields without resistance to a skewer inserted through all layers, the rice is fully swollen and has absorbed the surrounding liquid, and the Pecorino across the top is deep golden and faintly crisped at the edges.
5
Remove the tiella from the oven and allow it to rest, uncovered, for at least 10 minutes before carrying it to the table. The surface crust should hold its colour and not steam back to pallor during resting. Serve directly from the vessel.

Quality Hierarchy
01
Reserve — Small wild mussels from the Mar Grande of Taranto or the Adriatic coast of Puglia, harvested to order; stone-ground local Pecorino from the Murgia plateau; first cold-press Coratina olive oil from the Bari hinterland; rice from the Po delta selected for the variety.
02
Estate — Live farmed mussels from a single named producer, purged and graded for uniform size; aged Pecorino Romano DOP; a high-quality southern Italian extra-virgin olive oil; Carnaroli or Vialone Nano rice.
03
Market — Live rope-grown mussels from a reliable fishmonger, scrubbed to order; Pecorino Sardo or Pecorino Toscano; a decent Puglian or Sicilian extra-virgin olive oil; any short-grain rice sold for risotto.
04
House — Pre-packed live mussels from a supermarket chiller, thoroughly purged at home in cold salted water; a hard grating cheese substituted for Pecorino as a last resort; a neutral olive oil; standard short-grain or arborio rice.

Sensory Tests
◇Sight. The rice layer lies perfectly flat and uniform — no ridges, hollows, or exposed potato visible through the grains — before the mussels are placed on top.
◇Sight. Once the cover is removed, the liquid visibly sits below the surface of the rice rather than above it, signalling that absorption is advancing correctly.
◇Touch. A skewer passes through potato, rice, and mussel layers without resistance, confirming the potato is fully tender and the rice cooked through.
◇Sight. The Pecorino crust across the top is deep golden and dry at its edges, with no pale or wet patches remaining.
◇Smell. The brine of mussel liquor has mellowed into a rounded, olive-oil-sweet aroma with no sharp raw shellfish note — the signal that the liquor has been fully absorbed and cooked into the rice.
◇Where it lives or dies. The rice must be laid flat and even before the mussels go on top — it cooks solely by upward absorption of mussel liquor with no stirring to redistribute heat, so any unevenness at this stage is permanent.
