I have historically frequently bought Boar's Head meats from the deli counter because I can get them sliced prosciutto thin and they have the texture to support that. And the overall flavor experience when buried in a creatively built sandwich is "not terrible". Absolutely revolting when compared directly against handmade pastrami, ham, corned beef etc., but not bad in a sandwich.
However: in the last year I have noticed Boarshead moving more of their cured charcuterie meats into "nitrate free", which is a lie, they use celery instead, but of course that degrades the texture and flavor a bit.
So now I just buy the house brand meats when I'm slumming, and make my own pastrami, ham, and corned beef from time to time. For two olds a 5lb batch of cured meat is a lot. Like 6-12 months. But homemade charcuterie is so astoundingly good.
So no, I don't consider Boar's Head a premium brand. At least, not anymore. I smell enshittification at work.
Also, everybody should have the chance to try out real charcuterie.
