Notes
Blanch the fava beans for 2-3 minutes, then transfer them to ice water to stop the cooking process.For an extra layer of flavor, sauté the blanched and peeled fava beans with minced garlic in olive oil or butter for a few minutes.Slice the red onion very thinly to avoid overpowering the other flavors in the salad. Soaking the slices in cold water for a few minutes can also mellow their sharpness.
