Ingredients

  • 1 1/2 cups dry fino sherry
  • 1/4 cup turbinado sugar or palm sugar (See Note)
  • 1/2 pound rhubarb, trimmed and sliced diagonally 1/3 inch thick
  • 3 tablespoons unsalted butter
  • 1 pound bulb onions or sweet white onions, thinly sliced
  • 1/2 cup chicken stock or canned low-sodium broth
  • 1 thyme sprig
  • Salt and freshly ground pepper
  • 1 pound fava beans, shelled
  • Four 6-ounce salmon fillets, skin on
  • Vegetable oil
  • 1 teaspoon fresh lemon juice

Method

  • In a medium saucepan, combine the sherry with the sugar and cook over high heat, stirring occasionally, until the sugar is dissolved.
  • Add the rhubarb and cook until just tender, about 1 minute.
  • Strain the rhubarb in a colander set over a bowl to catch the cooking liquid.
  • Return the liquid to the saucepan and boil over high heat until reduced to 1/2 cup, about 8 minutes.
  • Melt the butter in a medium saucepan.
  • Add the onions and cook over low heat, stirring, until softened, about 1 minute.
  • Add the chicken stock and thyme sprig and a pinch each of salt and pepper.
  • Cover and simmer over low heat until the onions are tender, about 8 minutes.
  • In a medium saucepan of boiling salted water, cook the fava beans for 2 minutes.
  • Using a slotted spoon, transfer the beans to a bowl and refresh under cool running water.
  • Peel off the tough bean skins and add the favas to the onions.
  • Heat a cast-iron skillet.
  • Lightly coat the salmon fillets with some vegetable oil and season with salt and pepper.
  • Cook the salmon, skin side down, over moderately high heat until the skin is very crisp, about 4 minutes.
  • Turn the salmon and cook over moderate heat until barely cooked through, about 4 minutes more, depending on the thickness of the fillets.
  • To serve, discard the thyme sprig and rewarm the onions; add the lemon juice and season with salt and pepper.
  • Bring the sherry-rhubarb liquid to a boil and add the cooked rhubarb.
  • Spoon the rhubarb onto 4 large plates and set the onions alongside.
  • Top with the salmon and serve at once.
