Popular worldwide, cumin is a fairly pungent spice that is used to flavor many traditional Indian dishes. It has quite a powerful aroma and taste, so when using cumin, use it sparingly, as some types of cumin are stronger than others.
Before using it for the first time, you might want to take a little smell. That should be a good indication as to whether it is a suitable spice for you to use in your cooking. Most people either really like it or hate it.
