I’m a northerner and sad to say that corned beef is in the same category as spam. Something that should’ve been phased out with ration cards.
I’d agree with you on spam but as much as I hate it I strangely can’t resist the battered variety,I think it’s a ‘70s school thing where you were fed it so often and green custard and hard choc crunch.
TBH I used to eat chitterling with vinegar a kid until I found out what it was and I’m soft southerner stock.
