Ingredients

1 1/2 pounds red seedless grapes

1 tablespoon confectioners’ sugar

1 tablespoon extra-virgin olive oil

1 tablespoon minced shallot

1 tablespoon white-wine vinegar

1/2 teaspoon finely grated lemon zest, plus 2 teaspoons fresh lemon juice

1/4 teaspoon ground cumin

1/4 cup extra-virgin olive oil

Coarse salt and freshly ground pepper

2 celery stalks, thinly sliced crosswise, plus 1/2 cup leaves

1 head frisee, trimmed

1 Honeycrisp apple, thinly sliced

1/2 cup walnuts, toasted

Preparation

Roast the grapes: Preheat oven to 350 degrees. Toss grapes with sugar and oil. Roast on a rimmed baking sheet until just starting to wrinkle and burst, 25 to 30 minutes. Let cool.

Meanwhile, make the dressing: Combine shallot, vinegar, lemon zest and juice, and cumin in a bowl. Gradually whisk in oil. Season with salt and pepper.

Make the salad: toss grapes (without pan juices) with sliced celery and leaves, frisee, apple, and walnuts. Drizzle salad with dressing, and toss to coat.
