I'm from the south. My family always has deviled eggs at gatherings. My wife's family is the same way. I only make them for the older generations when we host a larger gathering. Deviled eggs are always "just okay." I guess they're a good way to pump some fat and protein into a crowd with a semi-shelf-stable, picnic-friendly snack or whatever. But... I don't know. They're just kinda "meh."
When I was a kid, I'd have my mom make me two eggs that were just whites, no filling. I ate those with salt and pepper. My mom overcooks her hardboiled eggs and that my mother in law is afraid of mayonnaise. My side of the family didn't put chopped pickles or relish in their eggs, but we adopted that practice from my wife's side.
I've been wanting to do a "fine dining" style riff on them for years to see if I can do something that's actually delicious. I'd strain a bunch of yolks and then cook them sous vide at 62 or 63 for like 30-40 minutes agitating frequently, then move them to a piping bag. Inside the white, do a dab of Momofuku's actually-quite-spicy chili crunch, a piped layer of kewpie, then the yolk and garnish with some chives or ikura (or chives and ikura). Or something like that.
