Walnut oil gives this salad a distinctly nutty flavor; it can be found in most grocery stores. Radicchio di Treviso has narrow, tapered leaves; radicchio di Verona leaves form loose, round heads. The varieties may not be clearly labeled, but the shapes make them easy to distinguish.



Ingredient Checklist


Instructions Checklist
  • Whisk together vinegar, salt, and pepper in a large bowl. Add oil in a slow, steady stream, whisking until emulsified. (If using olive oil, you may want to warm the oil and walnuts first over low heat in a small pan for a few minutes. Then let cool to room temperature to infuse the oil with flavor.)

  • Add radicchio to dressing, and toss. Divide among 4 serving plates, and sprinkle with walnuts.
