I used a honey crisp apple for this. You can choose whatever type of apple you like. It doesn’t have to be sweet!
If it’s not gingery enough for you, try adding a half tsp of dried ginger to the sauce and mix well.
To shred the cabbage, you can cut it very finely (which is my preference) or you could use a mandolin. The carrot and apple can be grated on a cheese grater.
To peel ginger, use a spoon to scrape the skin off.
