Every April the town of Vidalia, Georgia pays tribute to their most famous cash crop, sweet Vidalia onions.

I’ve loved Vidalia onions since childhood; one of the many pleasures of spring. Not an idea that makes most children’s hearts go pitter patter—“onion casserole, yes, please!”—but my grandmother used to make a gratin: a delicious blend of Vidalias, cream and Swiss cheese that rocked my world and made me realize onions could be a delicious entity in their own right, not just a hamburger topping or one of the bit players floating in a vegetable soup. 

The unique product of a 20-county area of Georgia and the state’s official vegetable since 1990, the Vidalia was the serendipitous discovery of Thirties-era farmer Mose Coleman, credited as the first grower of this milder onion variety. Every April the town of Vidalia celebrates their most famous crop with the Vidalia Onion Festival with the requisite Golden Onion Vidalia-cooking contest and the election of a Miss Vidalia Onion.

In honor of the annual spring Vidalia harvest, chef Marc Taft of the farm to table restaurant Chicken and the Egg in Marietta, Georgia does a decadent version of Vidalia onion soup served with chicken liver mousse, Vidalia onion jam and candied bacon crostini. The recipe was Taft's Golden Onion entry in last year's Vidalia Onion Festival.
