The one that surprised me the times I've been over was your tinned beans.
I misspent my youth as an unenlightened eater of canned "Boston baked beans" (which are always way too sweet with corn syrup and weirdly thin sauce, but actually really lovely if made properly at home from scratch). I was certainly beans-n-toast-curious before those trips, but now I'm full-Irish bean-pilled!
I've tried all the English brands we have here, and some of those are nice, but almost any Irish tin will beat any of those. We can reliably get batchelor's here in the States, so I'm fully graduated now to cracking open that greenish blue tin, heating on the stove til "stodgy", just a shot of Worcestershire to kick up the umami, and on to hot BUTTERED toast, oh man. If I'm feeling fancy I'll even grate some Dubliner reserve or something and crack some white peppercorns over the top. Perfect with a cuppa on these snowy and frigid New England days. Chef's kiss 🤌
Please do let me in on any other Irish bean recs if you have em. My "actually Irish" peeps eventually got sick of my ranting about something as mundane as tinned beans but I felt like Anthony Bourdain discovering some long lost dish from an ancient cuisine for a minute. I do love a great deal more about your country than just the bean tins lol, but it's nice to have that accessible at home to "feel Irish" for a minute haha.
