The Plain People of Ireland: Connemara Kitchen®? So this would be a Traditional Irish Toffee, would it?
It would indeed.
TPPoI: And would this toffee have been bought by someone in Ireland itself.
That would be the case.
TPPoI: Perhaps by someone who was returning from a trip to our Isle, and who wished to bring his colleagues a taste of our fair country?
That would be quite likely, yes.
TPPoI: And the timing, sir. If these toffees didn't appear till today, then presumably the person would have still been away yesterday.
That sounds plausible.
TPPoI: So tell me: when were you this time yesterday?
Why, we'd just taken off from Dublin airport.
