How to add Heading to a Sidebar - NOT how to change widget title

Hi there,
As the title says, I'm trying to figure out how to add a title/heading to a sidebar before widgets display. I found the answer on how to do that for the center column, but the sidebars have me baffled. You can see here (http://test.ramblingspoon.com/) the center title configuration ("Entrées") I'm trying to get above the sidebars.
Much thanks in advance.
