Ingredients

  • 3 1/2 cups Italian sparkling mineral water (or tap water), plus more as needed
  • 1 tablespoon kosher salt
  • 1/2 cup polenta (preferably whole grain or from an artisan mill)
  • 2 tablespoons extra-virgin olive oil
  • 1/4 cup finishing-quality extra-virgin olive oil
  • Fresh coarsely ground black pepper
  • Wedge of Parmigiano-Reggiano, for grating

Method

  • Combine the water and salt in a large saucepan and bring to a boil over high heat.
  • Gradually add the polenta, whisking constantly.
  • Stir in the olive oil and bring the water back to a boil.
  • Reduce the heat and cook the polenta at a very low simmer until its creamy, for 40 minutes to 3 hours, adding more water to the pot as needed.
  • You can prepare the polenta to this point up to three days in advance.
  • Set the polenta aside to cool to room temperature, transfer to an airtight container, and refrigerate until you are ready to serve it.
  • Just before serving, warm the polenta over medium heat, stirring often and adding enough water to loosen the polenta to a creamy consistency.
  • Drizzle the 1/4 cup finishing-quality olive oil into the polenta, stirring vigorously to emulsify.
  • Transfer the polenta to a serving dish or individual dishes.
  • Drizzle a thin layer of additional finishing-quality olive oil and coarsely grind fresh pepper over the top.
  • Use a microplane or another fine grater to grate a thin layer of Parmigiano-Reggiano over the polenta, and serve warm.
