Ingredients

  • 4 medium or 8 small leeks, white and tender green
  • 3 tablespoons rice vinegar
  • 1 tablespoon fresh lemon juice
  • 2 1/2 teaspoons Japanese light miso paste
  • 1/2 teaspoon Dijon mustard
  • 1/2 teaspoon mayonnaise
  • 1/2 teaspoon minced fresh ginger
  • 1/8 teaspoon cayenne pepper
  • Pinch of salt
  • 2 tablespoons extra-virgin olive oil
  • 1/4 cup peanut oil
  • 2 tablespoons thinly sliced red bell pepper

Method

  • In a medium saucepan of boiling salted water, cook the leeks over moderately high heat until tender when pierced with a knife, about 12 minutes for medium leeks and 8 minutes for small ones.
  • Refresh the leeks in a bowl of cold water for 1 minute, then drain and pat dry.
  • Halve the leeks lengthwise.
  • In a blender or food processor, combine the vinegar, lemon juice, miso, mustard, mayonnaise, ginger, cayenne and salt and mix for 30 seconds.
  • With the machine on, gradually add the olive oil, then the peanut oil and mix until completely smooth.
  • Scrape the vinaigrette into a bowl.
  • Spread the cut sides of the leeks with about 2 tablespoons of the miso vinaigrette so it permeates the layers.
  • Cover and refrigerate until ready to serve.
  • To serve, drizzle the leeks with the remaining vinaigrette and garnish with the sliced red pepper.
  • Serve chilled or at room temperature.
