I grew up in the Carolinas and ate a lot of BBQ in both. But there's so much bbq and so much variety that I think mostly people are experts in what they've eaten.
A+ ... S. Carolina--mustard-based sauces, a holdover from german immigrants, pulled pork only ... Can't even name a place, I ate so much of it growing up. Just not the racist mofo downtown.
A++ ... N. Carolina--vinegar-based, a wider range of pork cuts, still mostly known for pulled pork... Allen & Sons, around Chapel Hill, is awesome.
A+ ... Memphis--I just remember sauce and smoked meat.
A++ ...
Kansas City I ate it all and it was all wonderful
A+++ ...
Texas. Texans do their bbq right and well and good and it is the best.
I ate in a bunch of BBQ joints travelling a few years back, but Texas was really something else. And not just LA BBQ, which is in a trendy hipster area .... it was fantastic, but so were the roadside places doing goat
Texas BBQ may well be a different subset of BBQ.
Having grown up with saucy-pulled pork sandwiches, I can firmly say less sauce and more good meat is the way to go. NC makes really really good pulled pork. Maybe the best.
But it's BBQ. As long as there's some effort and real ingredients in it, I'll probably love it.
