When you think of a pepper mill, you might not realize that there are several different names for this kitchen tool. A pepper grinder is a common synonym for pepper mill, but there are other options as well. Some people refer to it simply as a spice mill, which is also appropriate since you can use it to grind other spices like cinnamon or cloves. The word "grinder" can also be used instead of "mill," and you might hear it called a pepper shaker as well. No matter what you call it, this tool is essential for adding freshly ground pepper to your meals, and it's worth having in your kitchen.
