For the non-gastronomically nerdy, Berkshire pork is highly valued because it is super marbled (think Wagyu beef).

Went to Pied-a-terre and they did a phenomenal job.
Never even considered getting my hands on it, just assumed it'd be too pricey.
So if anybody's got a good source, share the wealth!
