It's not because I am passionate about eating, love writing and want to share my kitchen experiences with others. I mean, those things are all true and they contribute to why I do what I do, but alas, they are not why.
No, the core reason is that I dislike being told what to do so much that if you give me a recipe to follow, I will become so annoyed and resentful that I will, whether consciously or unconsciously, find a way to screw it up. It may still turn out well, but it will not turn out the way you expected it to, because you and this recipe are not the bosses of me, dammit. It's easier, I've found, to just make up the recipes myself.
