As a sort of retired baker, I like breads and cakes. I like trying out different things that might work with bread or cake. For an example, a bit of finely chopped jalapeno goes with dark chocolate, like some people put chili powder in chocolate. I like to find different things that work with "usual" cakes and breads.
I have a friend who loves my strawberry bread, so I make that for her once in a while. I have found that a bit of crushed, dried basil goes with French Vanilla cake very well, and a bit of crushed, dried dill goes with lemon cake. Well, to my liking anyway.
So I have always been an experimenter when it comes to cake, breads, cookies, etc.... as I don't like my sweets all sugary sweet, so besides adding less sugar, I try to find out what can be added to make it not so sugary sweet.
As for breads, it's the opposite. Some standard bread recipes can be a bit dry, bitter, or just BLAH, so I try to find something that can add a bit of moisture or "pizzazz" to it, without taking away from the bread aspect.
