There are quite a few places all within a few minutes of my house which sell it. Of course you can buy it online, but if you are in close location to a town where there are Turkish/Middle Eastern grocery stores they are likely to have it stock.
Polish supermarket deli sections can be a temple of ham.
How many of types of ham do you have?
All of them.
A friend of mine loves ham more than life itself and has worked his way through most of it not all the ones in Streatham (which has a sizeable Polish population). The grey brown looking Roasted ham might not be too appetizing to the eye but it's a gem of a ham, works well in sandwiches but at it's best stood in front of the fridge and eating the ham from the packaging.
I'm a fan of the rolled cured neck of pork as well.
One thing both the Turkish and Polish supermarkets have which I am a fan of are whole Walnuts. One of my favourite snacks, and an underrated nut - the cashew seems to get a lot of glory but I prefer the walnut.
Not really entire what the point of my post was but here it is nonetheless.
