King Cake?

I’ve been thinking I’d make a King cake this weekend, but I’ve never had one and now as I look at recipes, I find three variations!

There’s one from Food Network that has a raisin and pecan filling, I’ve found another that has cream cheese and one with no filling at all…

Then there’s the cake itself, all say round like a doughnut, but one called for it to be braided (the one without a filling obviously)…

I don’t mind the work, but I’m not sure which version is “authentic”. Does anyone out there know?
