Of late, a number of spice companies have been covering their jars with lids that grind. You twist as you dispense the contents, grinding the herbs and spices to release the freshest flavor. As a longtime advocate of fresh grinding, I view this as a step forward in good taste. And the concept is spreading. On a recent whirlwind tour of spice production around the world, hosted by Spice Islands, I even came across jars of black peppercorns topped with grinding lids in India. Closer to home, several companies are packaging spices, herbs, and salts this way; many offer blends, and some have citrus zests or flowers. They include Melissa's My Grinder (800/588-0151 or www.melissas.com for sources) and the Elements of Spice (800/451-7647 or www.elements-of-spice.com). You may pay a small premium for the grinder, but it will usually last long enough for you to refill the jar several times.
