Grinding your own spices might seem laborious and unnecessary when you can buy them pre-ground, but spices are like coffee beans in that their flavor has exponentially more character when freshly pulverized. Whole spices are also more cost-effective than ground spices and have about twice the shelf life. Freshly ground spices pack a serious punch, and you won’t have to use too much to make a flavorful meal. Grind cloves, nutmeg, cinnamon, cumin, dried chili peppers, and more. Many of these grinders are great for grinding nuts and herbs as well. Spice grinders come in many shapes and sizes—some manual, some mechanical. Here’s a list of some of our favorites to help you find what’s right for you.
