I like Porkinson Bangers
Outdoor Reared British Pork Shoulder (80%), Water, Rusk (Wheat), Salt, Flavourings, Herbs, Stabiliser: Diphosphates, Preservative: Sodium Sulphite, Spice
They have a pork protein case.
Or Waitrose free range pork sausages
Pork shoulder (61%), pork belly (26%), water, rusk, salt, wheat flour, spices (pepper, nutmeg, ginger), preservative sodium metabisulphite, autolysed yeast, mustard seed, wheat dextrose, spice extracts (pepper, nutmeg, mace and cayenne), herb extracts (sage and thyme) Rusk contains wheat flour, salt, yeast, raising agent ammonium bicarbonate Product as sold contains pork 87% Filled into natural sheep casings (2%).
I think these both taste good, and the children agree. When we shop at Sainsburys/Tescos, I usually don't buy sausages (we only do Waitrose/Ocado about once a month when I have really run out of nice food)
