Roasted Marrowbones with Sel Gris

For hundreds of thousands of years, we burned bones in the fire and then broke them open to slather our food (and faces and bodies) in the butter-fine marrow. Scooped from roasted veal bones and spread on a wedge of crusty bread, marrow is so rich and flavorful that it threatens to overwhelm. And that’s where the salt comes in. The strident mineral tones of a coarse sel gris penetrate through the fatty richness, letting fly its myriad dimensions—like cutting a ruby from a hunk of Burmese rock. If marrow hadn’t been created by nature, it would have been necessary to invent it just to have a food that strikes so squarely at the core of the eating experience. If it weren’t for sel gris, nature’s felicity would all be for naught.
