The shrimp here are served in a molcajete, a large bowl carved out of lava rock and sent to the table bubbling hot and furious.
The dish is called Camarón Azteca, and the volcanic container keeps the fresh-from-the-oven meal wickedly warm. It's a good thing, too, because it takes us a long time to work our way through the Vesuvius-size mound of Guaymas shrimp; in any other dish, the shrimp would get cold.
Much of the magic in the bowl comes from its voluptuous sauce, essentially chunky, chile-rich salsa blended with Mexican white cheese. We're told there's no butter involved, but it sure tastes of it -- a reaction of the milky cheese melted at such high temperature, we suppose.
