What a pity. Down here even the regular grocery stores will have Kerrygold (grass fed Irish butter), and the fancy gourmet stores will have imports from Iceland and France and Belgium and New Zealand as well. My favorite is Isigny Ste Mere.
None of us have the nerve to do it.

But I'm also so curious as to how this is going to work, I may just try.
