Ingredients

  • 1 tablespoon fennel seeds
  • 1 small red onion, very thinly sliced
  • Fennel fronds from 1 fennel bulb
  • 1/4 cup kosher salt
  • 2 tablespoons sugar
  • One 2-pound striped bass fillet, with skin
  • 1 cup grappa
  • Toasted baguette slices, extra-virgin olive oil and coarse sea salt, for serving

Method

  • In a small skillet, toast the fennel seeds over moderate heat until fragrant, about 1 minute.
  • Let cool.
  • On a rimmed baking sheet, spread the onion slices in the same shape as the fish fillet.
  • Top the onions with most of the fennel fronds, reserving a few for garnish.
  • In a small bowl, mix the salt with the sugar and fennel seeds and sprinkle over the fennel fronds.
  • Set the fish on the curing mixture, skin side up, and pour the grappa over the fillet.
  • Cover with plastic wrap.
  • Set a baking sheet on top of the fish and weigh it down with heavy cans.
  • Refrigerate for 24 to 36 hours.
  • Unwrap the fish.
  • Drain and scrape off the curing mixture; transfer the fish to a cutting board, skin side down.
  • Using a thin-bladed knife and starting at the tail end, thinly slice the fish on the diagonal.
  • Avoid the darker flesh near the skin.
  • Serve the slices on toasts drizzled with olive oil and sprinkled lightly with coarse sea salt and fennel fronds.
