Changed My Label System

You will notice a new look to the side bar labels.  My labels began to have too many cross references.  The labels are supposed to resemble an index in a cook book, however, there isn't a way to break down the labels to subsets.  For example, in a cook book you see 'Meat' broken down further into sub groups, for instance Chicken, Beef, Pork, Lamb, etc.  I like that system and am searching for a way to list my recipes in that fashion.  If it can't be done on this blog, I may move my blog to a location where that is an option.  Any feedback is welcomed!!  The comments section is open to all.
