Cover bowl with plastic wrap and chill for 1 hour or overnight.
Step 6
Meanwhile soak casing in cold water for about 30 minutes. Place the wide end of a small sausage-stuffing funnel up against the sink tap and run cold water through the inside of the casing.
Step 7
Use the medium sausage-stuffing funnel attachment and place casing on the outside of the tube. Start passing meat mixture through the funnel stopping just as it starts to come out the other end. Tie the casing into a knot at the end then continue passing the meat mixture through the funnel supporting the sausage with your other hand. Once the meat mixture is finished tie the other end of the casing into a knot.
Step 8
Twist the casing at regular intervals to create individual links alternating between twisting in opposite directions. Poke 2 to 3 small holes into each sausage with a metal skewer to allow air to escape during cooking.
Step 9
Cook as desired or chill in the fridge for up to 3 days.
