My 47 year old neighbour tells me that all the beef farms around here used to keep pigs as part of their smallholding life. The baker and grocer still visit each cluster of 4-5 homes but most homes were self sufficient in veg, fruit, eggs, poultry and pork.
Apparently there was a rota for home killing a pig with neighbours helping with the kill,burchering and processing. Hams were hung in the loft to dry or smoked, pork was salted in large clay pots but fresh cuts were distributed to other pig keepers who would return the act when they killed their pig.
What a mission! We home kill, butcher and make hams,bacon and sausages and simply dump the rest in freezers. I know this to be pretty full on but imagine having to preserve as much of the pig as you can (without a freezer) and distributing other cuts amongst other homes in the area.
We are the only household keeping pigs in our hamlet but neighbours and even their home help bring veg and fruit for the pigs to eat - they get some pork in return.
I guess the advert of the freezer changed relationships between rural communities.
