For me, the margarine v. butter debate was never a debate at all. I'm a butter man, through and through. My father was a butter man, as was his father before him. The mere mention of margarine or (shudder) that faux-butter stuff Fabio hawked was met with utter disgust in my house -- and I'm a better person for it.
Still, there is a healthy constituent of margarine enthusiasts out there who beat their chests and decry that butter is evil in dairy form. But the mastermind behind the renowned restaurant Noma, René Redzepi (you may know him as the chef who thinks we should be snacking on live ants) has once again turned to the natural world for culinary purposes -- this time, for advice.
