If I had thought the beef marrow might be a hell of a lot of work for not much difference, I needn't have worried. The taste of the marrow is rich, meaty, intense in a nearly-too-much way. In my increasingly depraved state, I could think of nothing at first but that it tasted like really good sex. But there was something more than that, even. What it really tastes like is life, well lived. Of course the cow I got marrow from had a fairly crappy life - lots of crowds and overmedication and bland food that might or might not have been a relative. But deep in his or her bones, there was a capacity for feral joy. I could taste it.
