evil foods?

[jacambece]

I was taking out the trash and I noticed a box of devil cakes and another box of devil dogs, this made me think. What makes "devil" Food? Both are snacks (I guess) are the made with devils food cake? Then I started thinking about deviled eggs...what makes the eggs evil? Sorry in advance for the off topic-ness of this I just want to know if it’s marketing by saying "it’s so good its sinful" or if there is a reason behind using devil in the name.

"deviled - (1) A term describing food that is dark, rich, chocolate, spicily piquant or stimulating it is "deviled." Means a highly seasoned, chopped, ground, or whole mixture that is served hot or cold. Many foods, including eggs and crab, are served "deviled." Source.

Probably due to thinking that anything tasting that good must be sinful.
