1. How should I eat this?
In front of you, on the plate, goose barnacles. Once you accept those weird sea hooves are actually eatable, the shyer ones will discreetly look around to see what locals do and try to imitate them as well as they can. The rest will look at the plate, and then look up and ask the question. This might also happen with oysters, small crabs, and other marine delicatessen.
