...if we really want to speak of roots, let us rely on metaphor all the way, and let us imagine the history of our food culture as a growing--not a shrinking--plant. It gradually burrows into the earth, seeking vital nourishmwnt wherever it can, implanting its rootsprecisely in places as distant as possible(soemtimes unimaginable.) The product is on the surface--visible, clear and well-defined: that is us. The roots are underneath--generous, numerous and diffuse.
