I asked about this on iTalki but didn’t get any useful answers. The hotel we stayed at earlier this summer had pepper grinders on the table, but instead of having normal black peppercorns in them, they had allspice (aka Jamaican pepper). I wondered if this was common in Portugal or if someone had just got confused in the hotel kitchen.
I still don’t know, but if anyone else does, I’d be interested to hear about it.
