Ingredients

  • 2 tablespoons olive oil
  • 1 onion, minced
  • 4 pounds well-trimmed boneless lamb shoulder for stew, in chunks
  • 2 1/2 cups lamb, chicken or beef stock, approximately
  • 2 tablespoons potato starch
  • 2 cups heavy cream
  • 6 egg yolks
  • Juice of 4 lemons
  • Salt and freshly ground black pepper
  • 1 tablespoon chopped fresh mint

Method

  • Heat the oil in a large, heavy casserole, add the onion and saute until it is translucent.
  • Stir in the lamb and add the stock, using enough to cover the lamb.
  • Bring to a simmer; cover and cook over medium-low heat until the lamb is tender, about 45 minutes.
  • Remove the lamb from the broth.
  • Strain the broth and remove as much of the fat as possible.
  • You can do this by starting the preparation the night before and refrigerating the lamb, covered, overnight and also refrigerating the stock.
  • When the stock has chilled sufficiently, the fat can be lifted off and discarded.
  • Shortly before serving, measure the stock.
  • You should have about two cups.
  • Add a little water if there is less.
  • If there is more you should plan to increase the amount of potato starch proportionately.
  • Slowly beat some of the cream into the potato starch, beating to blend the cream and the starch together.
  • When the starch is liquefied stir in any remaining cream.
  • Bring the stock to a simmer in a casserole.
  • Whisk the egg yolks and lemon juice together in a bowl.
  • With the stock barely simmering, slowly whisk in the egg-yolk mixture.
  • Then slowly beat the cream mixture into the stock mixture.
  • Cook slowly, about five minutes, until the stock thickens and becomes sauce, then return the lamb to the sauce.
  • When the lamb has been sufficiently reheated, season the sauce to taste with salt and pepper.
  • Transfer the stew to a warm serving dish, sprinkle with the mint, then serve.
