I learned to make this by watching my mom, so I don't really have an exact recipe. But, this is my best guess:
1 package of cole slaw mix (you could shred your own cabbage and carrot, but this is so much easier)
2-3 heaping spoonfuls (big spoon size) of mayonnaise
about 1/8 cup of sugar
about 10 shakes of red wine or apple cider vinegar (shake from a bottle with a rectangular opening)
about 1/2 tsp of horseradish (red or white, doesn't really matter)
pepper to taste
Optional: slivers of apples, raisins, or halved grapes - for a little extra sweet explosion
