where in Atlanta can I find?

Have you tried Trader Joe's. Whole Foods, Harry's?

I've never looked for it but Publix might have it too. Some of the upscale Publix stores may carry it.

I have to admit Atlanta isn't exactly a hot bed for great Italian food but if you Google "Italian Deli Atlanta" you'll get several delis and markets specializing in Italian foods.

Try this one. Toscano & Sons Italian Market,1000 Marietta Street, Suite 106, Atlanta, GA, 30318

Here's another. E. 48th Street Market, 2462 Jett Ferry Road, Williamsburg of Dunwoody Shopping Center, Dunwoody, GA, 30338

Last one. Buckhead Italian Market, 3655 Roswell Rd - Atlanta, GA - 30342

Ther are plenty more if you just google it.

I would try any of the Whole Foods/Harry's, and the DeKalb Farmers Market. If you have no luck, try callihg an Italian bakery, since it's frequently used in cheesecake. They would probably sell you a container.
