Molcajete [mohl-kah-HEH-teh] What? The ancient Cuisinart. The Mexican word for a heavy, three-legged mortar, the molcajete is never without its trusty counterpart, the tejolete [teh-hoh-LEH-teh], the Mexican pestle. The pair are made from basalt, or lava rock, and are used to grind tomatoes, tomatillos, and spices into thickly textured, tasty purées. Molcajetes are usually 8 inches in diameter, 5 inches high, and hold one quart of sauce. The most effective ones are not too porous. When? September 16, Priscila Satkoff, ¡Salpicón!, Chicago
