Encyclopedia of spices – try a new one or find which ones pair with which foods. Nice list
This is a fantastic site for information on spices. It tells which ones belong in which group and then tells you what types of food they are used in. Great source from The Epicentre for folks that like to try new things when cooking. The page loads on A and B spices, to see the rest hover over ENCYCLOPEDIA OF SPICES at the top in the red area.
