For the Humber's southerly denizens in particular, this nutritionally sound, quality comestible provides a mightily welcome change from the monotony of 101 ways to cook pig. Especially in winter.
These are, after all, the good folk who brought you that fatty bit of pork between the shoulder blade, salted for ten months, stuffed with parsley and simmered for ten hours, aka Lincolnshire chine. Local butchers supply that one strictly under the counter
And indeed, that spectacular delicacy haslett, of secretive provenance which -as far as I can establish - is highly seasoned toenails plus the squeak, but very tasty with a fried egg, or nice cold on a sandwich with a bit of piccallii.
I'll not dwell on brawn, (first boil pigs head for two hours, then press meat scrapings for 3-5 days in some cooking liquor, great in bread buns with branston though) but believe me, round here they make fergus henderson look a complete wuss..

'oss meat indeed
