Cut the cabbage finely or grate in a food processor. Grate the carrots as well. Add the vegetables together in a large bowl and add the raisins.
Make a large qty of dressing with the given ingredients and taste in between. The exact qty is depending on your taste, but if you start first with the amount of mayo you think you need you can build on that and add vinegar bit by bit till it is to your liking.
This salad is best if you make it a day before you're gonna eat and leave to sit in the fridge overnight
Notes
If you're doing a whole30 make sure your raisins are sugar free!
