A spice grinder is a kitchen tool that uses sharp blades or grinding mechanisms to finely chop or pulverize spices, transforming them into a powder or paste. It enhances the flavors and aromas of various spices, allowing you to easily incorporate them into your culinary creations. The combination of "🌶️" (representing chili peppers) and "🔪" (symbolizing the cutting action of the grinder) suggests the fiery intensity and precision with which a spice grinder can handle spicy ingredients.
