In a small bowl, whisk mayonnaise, vinegar, sugar, cumin, and pepper to make dressing.
In a large bowl, add dressing to shredded cabbage and carrots and mix thoroughly. Refrigerate to allow flavors to meld.
Toss again immediately before serving.
Notes
This coleslaw can be made a few hours ahead of time. Toss before serving.
Refrigerate for up to 3 days. When reserving, stir or drain if the coleslaw is too watery and refresh the dressing.
*To Toast Cumin SeedsAdd seeds to a small skillet over medium heat. Cook for 2-3 minutes, stirring often, until fragrant. Seeds tend to burn quickly, so be careful and continue to stir and shake the pan. Remove from heat and move to a small dish to cool.
