Getting hold of caul fat these days is not easy. The small local abattoir (themselves a dying breed) where we take our pigs, aren't allowed to let me have the caul fat or the blood or certain organs when they slaughter our pigs. Something about the regulations means they can't let us have that which is a shame.
I've home butchered (not slaughtered) a pig and a sheep on the dining room table and have a whole new appreciation of the butchers arts. For those interested, Scott Rea on YouTube is the man to watch, a master butcher teaching the skills all the way from 'how to tie a butchers knot' to 'how to butcher a cow'. I did our animals by having a laptop on the side of the table with the keyboard covered in cling film so I could pause/rewind/replay sections as needed. Easier than you think but much more tiring.
I've come a long way from 25 years as a vegetarian
