Ingredients
1 pound (about half a medium head) green cabbage, finely shredded 
Salt and freshly ground pepper 
1/2 small red onion, finely chopped 
1 tablespoon honey 
2 tablespoons rice-wine vinegar 
2 tablespoons olive oil 
1 teaspoon mustard 
2 teaspoons minced fresh tarragon leaves 
1 large Granny Smith apple, peeled, cored, and cut into 1/4-inch pieces 
1 medium head fennel, thinly sliced (about 2 1/2 cups) 
Preparation
Toss cabbage and 1 teaspoon salt in a colander or large mesh strainer set over a medium bowl. Let stand until cabbage wilts, 1 to 4 hours. Rinse cabbage under cold running water (or in large bowl of ice water if serving slaw immediately). Press, but do not squeeze, to drain; pat dry with paper towels. (Cabbage can be stored in a resealable plastic bag and refrigerated overnight.)
Stir together onion, honey, vinegar, oil, mustard, and tarragon in a medium bowl; set dressing aside. Immediately toss cabbage, apple, and fennel in dressing. Season to taste with salt and pepper. Cover, and refrigerate until ready to serve.
