It's supposed to be a helper app of some sort that various apps installed. TastyApps was one such vendor who have since stopped using it. Here's their text on how to remove it:
The simplest way to uninstall SpiceRack is to go to your System Preferences, click on SpiceRack and use the Uninstall button in the lower-left corner. If you have already deleted the system preference panel, or if you have an older version of SpiceRack installed where the uninstall option was not available, you can instead use this AppleScript uninstaller.
Also note that the usual way to uninstall a third party preference pane is to right click on the item and choose "Remove xxx Preference Pane".
