The black ones are prunes stuffed with walnuts and cheese rolled in bacon. The lighter ones are chicken liver rolled in bacon. I ate most of them. My friend found the prune ones too sweet and the liver ones too dry. I liked them but the flavors are indeed intense. If you ate these everyday, you would be thoroughly sick of them. People with intense personality are not good for daily consumption. They are lots of fun to hang out with occasionally. Since I went to art school, I have many friends who are equivalent to these stuffed and bacon-wrapped prunes. After a while, they become too fun to be with.
I will email you when I post a new article.
