My Grandma was a wonderful baker, and had a secret cake recipe that she had created herself. It used some very uncommon spice combinations in the cake and frosting that produced a very unique but delicious cake.
When she got sick a couple years ago, she decided to share the recipe so that it wouldn't die with her, and offered to give it to any of her kids or grandkids who wanted it. I was the only one who asked for it before she died. I don't know why no one else did, as there were several other bakers in the family.
After she passed, I took over bringing the cake to family gatherings, and everyone was happy to still be able to enjoy it. I also started making cakes for friends & family, and then for others by word of mouth to make some extra cash on the side. My business was really starting to pick up.
