There are countless worthy options.

My bid won't rest on the usual drinks -Port wine; Vinho verde; Moscatel; vinho da Madeira, etc.

foodstuffs- pastéis de nata; queijadas; ovos moles; etc. -

even the most orthodox pieces of artisanship- i.e. galo de barcelos; traditional jewelry, typical instruments, etc.

I'm proposing something different that what most people wouldn't venture proposing.

I propose: Malandrice das Caldas

Because there's a dire lack of kitsch phallic decoration out there in the world
