My mom was an adventurous cook for her day. She would try some of the oddest (to a finicky teenager) recipes and all she would have to say is, "Don't bother, you won't like that", and BAM! I would dive in and eat it to spite her. (Cunning, wasn't she!). This dip is one that I wouldn't try on a bet, were it not for my mother's challenge.
Today, it is still a favorite of mine because it is relatively healthy snack food and I LOVE HORSERADISH!!! It is quick to prepare, and if you don't like it, then there is more for me!
Mom, always served it with raw turnip slices and I do to. It is good as a dip for any crudite. It is also good on baked potatoes.
