Ingredients

1 head garlic, 1/2 inch cut off top to reveal cloves

1 tablespoon extra-virgin olive oil

3 tablespoons red-wine vinegar

3/4 teaspoon coarse salt

1/4 teaspoon red-pepper flakes

3/4 cup (2 ounces) walnuts, toasted and chopped

Freshly ground pepper, to taste

1 pound shucked fresh fava beans (from 3 pounds pods; 3 1/2 cups)

2 cups fresh corn kernels (from 2 ears of corn)

1 medium cucumber, quartered lengthwise and thinly sliced

1/2 red onion, thinly sliced (1/2 cup)

2 tablespoons chopped fresh flat-leaf parsley

2 ounces feta cheese, crumbled

Preparation

Make the vinaigrette: Preheat oven to 350 degrees. Drizzle garlic with 1 teaspoon oil. Wrap in parchment, then in foil. Bake until soft, about 30 minutes. Squeeze garlic from skins. Mash until smooth.

Whisk together the remaining ingredients with 1 tablespoon of the roasted garlic and remaining 2 teaspoons oil.

Make the salad: Prepare an ice-water bath. Cook beans in a large pot of boiling water for 2 minutes. Using a slotted spoon, transfer beans to ice-water bath. Let cool completely, and remove with the slotted spoon. Cook corn in same pot for 1 minute, and drain in a colander. Peel thin shells off beans.

Toss cucumber, onion, parsley, feta, beans, and corn with the vinaigrette.
