Dressing: In a medium bowl, whisk dressing ingredients and season to taste with salt and pepper, then whisk until completely smooth. Refrigerate until ready to use.
Slaw: Thinly slice cabbage to make 7 packed cups (see note 1). Cut apples into matchsticks, about 3-1/4 cups (see note 2). Thinly slice celery and green onions. Combine all in a large bowl with almonds and cranberries.
Serve: Pour dressing over cabbage mixture and toss well. Refrigerate for 15–20 minutes to soften, then toss again, adjust seasoning as needed, and serve. Toss well occasionally during serving.

Notes
Note 1: How to prepare the cabbage:
Remove any outer leaves that are browned or crumpled.
Cut cabbage exactly in half.
Cut those halves in half (to get four quarters) and cut out the core of each quarter.
Slice each cabbage quarter into very thin shreds.
Transfer sliced cabbage to a salad spinner base. Wash thoroughly and spin to dry completely.
Note 2: How to prepare the apples:
Wash and fully dry apples.
Cut each side from the core to get four pieces.
Cut each piece into thin slices.
Cut each slice into thin slices that look like matchsticks.
Storage: For the best taste and texture, enjoy Apple Coleslaw the same day it's made. If you have leftovers, store them in an airtight container in the fridge for up to 3 days. Stir well before serving.
