Salt and pepper mills are an indispensable part of kitchen cooking and seasoning. Grinding your spices as you need them provides a fresher and more vibrant flavor. Season your meals using manual or electric spice grinders. It's easy to have more than one set, as many other spices taste better when freshly ground. In our home, we like to have different kinds of peppers and different kinds of rock salts, so a collection of spice mills is always at hand. There is also a set of salt and pepper grinders in a permanent spot at the dining table.
