I completely agree, and much of the work we do here is about subtley adapting methods and recipes to suit our own 'terrior'. This is how I farm and feed our Pigs and also how we make anything that comes from them.
This goes deeper than trying to adapt things so that we get as near to 'genuine' finished article as possible, its actually about trying to establish a taste and texture that we can think of as our own, not better, not worse, just different but with homage paid to the source
(As it happens I do have a customer 10 miles from Felino who prefers our version to what he can get locally
)
I appreciate the bayonne climate, and the river basin water and salt, but I have many similarities here in some ways, atlantic to the west, highlands to the east and widely varying humidity.
This is one of the things that has intrigued me about possibilities of a wine cured, slow drying ham with a dredge coating.
I will post details of the eventual recipe, techniques and results when they happen
