Chris's Sweet-and-Sour Slaw with Apple and Fennel

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.
