Dukes.
They don't sell it here in California, so for the past ten years, I've brought it back with me on the plane when I've visited my mom in North Carolina. Since 9/11, the TSA has opened my suitcase every time to examine the mayonnaise.
When friends and family come to visit me from North Carolina, they always ask what I would like for them to bring. Duke's mayonnaise is the only thing I've ever requested.
There are only thirteen more days until I move back to North Carolina and my Dukes mayonnaise.
