Start by shredding the cabbage finely using a grater or food processor, feeling the rough texture under your fingers and creating a vibrant pile of green or purple shreds.
Next, grate the carrots and add them to the bowl with the cabbage, mixing in their bright orange color and sweet crunch.
In a separate small bowl, whisk together the mayonnaise, apple cider vinegar, sugar, salt, pepper, and celery seed until smooth and well combined. This creates a tangy, creamy dressing.
Pour the dressing over the shredded cabbage and carrots, then toss everything together with a spatula until the mixture is evenly coated and glossy. Feel the crunch as you stir.
Thinly slice the red onion and fold it into the slaw, adding a sharp, pungent note for extra flavor.
Cover the bowl and refrigerate the coleslaw for at least 30 minutes, allowing the flavors to meld and the crunch to intensify.
Before serving, give the coleslaw a final toss, taste, and adjust seasoning if needed—add a squeeze of lemon or a dash more vinegar for extra brightness.
