Albania

As tradition built it

Serves 4 to 6. About 2.5 hours.

Ingredients

Method

  1. Salt the lamb, place it in a roasting dish with a little water, and roast at 200°C for about 1 hour, until well coloured.
  2. Whisk the yoghurt with the eggs, flour, a little salt and a spoonful of the meat's own roasting liquid, then stir in the melted butter.
  3. Warm this custard gently on the stovetop, 2 to 3 minutes over low heat, stirring, just enough to begin binding it; this is not a roux, and should not be treated as one.
  4. Pour the warmed custard over the meat, dot with a little extra butter, and return to the oven at 200°C for 35 to 45 minutes, until the surface is deep golden.
  5. The dish is ready when the surface is golden, the centre soft, and the meat separates easily with a fork.

What a modern chef changes

The custard's setting given the temperature control an oven can't offer.

Method

  1. Set the custard in a sous vide water bath at a controlled 82 to 85°C after the initial stovetop warming, before it ever meets the roasting lamb, producing an evenly, gently set custard with none of the risk of splitting or weeping a domestic oven's uneven heat invites.
  2. Roast the lamb separately to a precise internal temperature with a probe, then combine it with the custard only for the final browning stage, so the meat is never at risk of overcooking while the custard finishes.
  3. Finish the surface with a kitchen torch rather than extended oven time, achieving the deep golden colour without risking the custard beneath it.
