Query information from single table with parent-child relationship

I have a fairly simple database that is giving me issues.  The main table (tblCategory) is structured as such:

ID    Category    ParentCategoryID
1          Parent        NULL
2          Child           1

Ideally when I execute the query I would get the following results:
ID    Category    ParentCategoryID   ParentCategory
1          Parent        NULL                      NULL
2          Child           1                            Parent

This is the SQL query I wrote to try to pull the information:

SELECT ID, Category, ParentCategoryID, (SELECT Category FROM tblCategory WHERE tblCategory.ParentCategoryID = tblCategory.ID) AS ParentCategory
FROM tblCategory;

I know I could use two tables to do this; however the data structure for the both the parent and child recordsets are identicle.  I also like the idea of a recursive relationship data structure that could allow for infinite levels without having to create a table each time a new level of data is added.  

I appreciate your help and feedback.

The term to query is Common Table Expression and is completely related to SQL Server 2005
