Prep vegetables: Mix cabbage, carrot, and raisins in a colander. Pour in boiling water and let it run out of the colander into the sink. This will wash the vegetables, but also wilt them a bit. Let all the water drain and let the vegetables cool to room temperature.
Season: Mix in the mayo, season with salt to taste.
Chill and serve: Chill and keep refrigerated until it's time to serve.

Notes
The finer the cabbage is shredded (and carrots), the better the texture of the salad. If you don't have a lot of knife skills, my favorite way to get very thin cabbage is with a mandoline (Amazon affiliate link).Looking for a lighter, low-cholesterol option? Substitute mayo for my own choice of a vinaigrette consisting of a mix of two tablespoons of white wine vinegar, 1 tablespoon of olive oil, and one teaspoon of dijon mustard.
