It's recipes like these that I find easy to compare with sexual experiences. I promise you'll get some intense mouthgasms when you bite into one of these tarts. I did.
When basic logic is applied one can see how most - if not all - pleasurable moments in our lives are as such because of hormones. Namely endorphins, dopamine, oxytocin and the like. Some might think this is depressing, but I think it's totally awesome. Why do I love Jack? Well, for a lot of reasons that are unexplainable at the moment. But a huge part of it is because when I am around him and when I think about him, oxytocin is released in my brain! I associate positive emotions with him and my body and mind wants me to stick with the relationship because our evolutionary history values solid reproductive partners. When ya really give it a think - we are still such primal creatures. We are ANIMALS through and through. Sure, in the last several thousands of years our environment has changed - but our biology has not. Look around: we are uber preoccupied with eating, sex and... oh that's pretty much it. Of course we've got culture and art and music and important movements for social, political and environmental policy improvement; these seemingly have nothing to do with our fundamental drives but in a lot of cases I think you can still relate it back. There's no doubt that the general public is most focused on appeasing their senses. We are a sensual species! We like feelin' good. So do other mammals (because we are mammals, after all)!
