Cut the purple cabbage: Remove the wilted outer leaves. Halve, then quarter the cabbage using a chef’s knife. Slice off the bottom of each quarter at an angle to remove the core.1 lb purple cabbage / 450 g
Shred the cabbage: Place a wedge with the cut side down on a cutting board, then slice lengthwise into very thin strips. Halve these strips.
Prepare the other ingredients: Peel, halve, and thinly slice the onion halves. Halve, core, and cut the apple into matchsticks.1 small onion + 1 medium apple
Slaw dressing:
Combine the dressing ingredients in a small bowl. Taste and adjust the sweetness of the dressing.3 tablespoons sour cream + 2 tablespoons mayonnaise + 2-3 tablespoons maple syrup + 2 tablespoons lemon juice + 2 tablespoons white balsamic vinegar + 1 tablespoon dill + ½ teaspoon fine sea salt + ¼ teaspoon ground black pepper + 1-2 tablespoons milk
Make slaw: Combine the shredded cabbage, onion, and apple in a large bowl. Add the sour cream dressing and toss to combine. Adjust the taste with salt, pepper, and, if necessary, with more sweetener or vinegar; the slaw should taste sweet and sour.
Refrigerate the coleslaw for at least 1 hour before serving to allow the flavors to mingle.
Notes
Purple (red) cabbage: Depending on its size, you will probably only need about half of one head of cabbage.
Apple: A crisp, juicy, sweet-sour apple. I used Pink Lady, but Honeycrisp, Granny Smith, and the sweeter Gala are all excellent.
Dairy: You can replace sour cream with crème fraiche (more fat) or Greek yogurt (less fat).
Sweeteners: You can use other sweeteners like honey, agave syrup, sugar, or sugar alternatives like xylitol. It is best to use them to taste; the purple cabbage slaw should taste sweet and sour.
Vinegar: Substitute white balsamic with apple cider, red wine, or white wine vinegar.
