Ingredients

  • 1/2 bunch fresh mint, leaves only
  • 1/2 cup extra-virgin olive oil
  • 4 ounces thinly sliced serrano ham, prosciutto, or other salt-cured, unsmoked ham
  • 1/2 cup membrillo paste, also known as quince paste
  • 1 sourdough baguette, cut on the bias into 1/2-inch slices and toasted until golden brown
  • 4 ounces aged Manchego cheese, shaved into bite-size pieces with a vegetable peeler

Method

  • Bring a small saucepan of water to a boil over high heat.
  • Meanwhile, prepare an ice water bath by filling a bowl halfway with ice and water; set aside.
  • Blanch the mint by submerging the leaves for 10 seconds in the boiling water, then immediately placing them in the ice water.
  • Remove the mint from the ice water and pat dry.
  • Place the mint leaves and olive oil in a blender and puree until smooth.
  • Set the blender carafe aside and let the oil steep for at least 2 hours.
  • Strain through a fine-mesh strainer into an airtight container, cover, and set aside.
  • Heat the oven to 400 degrees F and arrange a rack in the middle.
  • Line a baking sheet with parchment paper and arrange the ham in a single layer on it.
  • Bake until the ham is crisp and golden brown, about 15 to 20 minutes.
  • Transfer the ham to paper towels to drain and cool, about 10 minutes.
  • Meanwhile, place the membrillo in a small bowl and stir until smooth.
  • When the ham has cooled, crumble it into bite-sized pieces and set it aside.
  • To assemble the crostini, spread a heaping teaspoon of the membrillo on each slice of the toasted baguette, then top with a few crumbles of ham and a shaving of cheese.
  • Drizzle a few drops of mint oil on top and serve.
