Dear Dr. Boli: The Food Festival supermarket in my neighborhood has started carrying Irish butter in the dairy department. But it’s much more expensive than butter from Pennsylvania dairies. So what is the difference between Irish butter and the local butters? —Sincerely, A Famous Chef Who Prefers to Remain Anonymous.

Dear Sir or Madam: Irish butter comes from Ireland. Is it Dr. Boli’s imagination, or are these questions getting easier?
