A spice grinder is a kitchen tool used to crush and grind whole spices into finer powders. This process enhances the flavor and aroma of spices, making them more potent when added to dishes. Spice grinders come in various forms, including electric models and manual options like mortar and pestle. Using a spice grinder allows cooks to create fresh spice blends tailored to their recipes. Common spices ground in these devices include cumin, coriander, and pepper. Freshly ground spices can significantly elevate the taste of meals, providing a more vibrant culinary experience.
