You asked for a standard UK style sausage recipe. However, as there are over 400 regularly prepared styles of sausage made throughout the UK I have posted one that I feel is reasonably easy to make. Adjust the quantities as required, definitely if you�ll be using a food processor in place of the bowl chopper.
London Trade Sausage (Pork Sausage) 67% meat content w/approx 27% fat
Ingredients
� 12 lbs lean pork (such as 95 vl pork shoulder, butt or loin)
� 3 lbs hard pork backfat
� 3 lb pinhead rusk (white 1/8 inch ,3mm dia)
Note: Rusk recipe previously posted or purchase some
� 4 lbs water (iced) - approximately 3 ⅓ pints (Imperial)
� � lb soya flour (70 %)
Seasoning
� 6 oz salt
� 1 � oz ground/powdered white pepper
� 1 oz ground/powdered mace
� � oz ground/powdered ginger
� 1 � oz ground/powdered sage
Method
1) Place the rusk in the water and set aside allowing for the rusk to take up the water. Note: Ratio of 1 � : 1 (water to rusk) used
2) Prepare lean meat, and pass through the mincer (3/8 inch, 10 mm plate)
3) Cube the fat (1/2 inch, 12 mm) and set aside
4) Place the lean meat into the bowl chopper/silent cutter
5) Add the seasonings, soaked rusk, and finally the cubed fat.
6) Continue chopping until the desired texture/consistency is achieved. In London, as in Scotland, a fairly fine texture is preferred.
7) Fill into narrow-medium hog casings (32-35 mm)
Link at eight to the pound.
9) Allow to dry for approximately 20 minutes then store in fridge or freeze.
Hope that this is some use to you
Kind regards
