I'm not saying that homemade sausages are easy to make, but it's lots of fun and you know exactly what's in it.
Turn on the machine, and push some of the mixture into the feed tube. When it emerges from the nozzle, curl your hand around the casing with the sausage mix in it and gently ease the skin off the nozzle as it fills up. Massage the length of sausage to try and get an even diameter. When you have about 30cm (a foot) of sausage, begin to coil it on the table - this keeps it neat and tidy and stops it falling on the floor. Keep on feeding the mixture in, massaging the extrusion and coiling the sausage until all of the filling is used up.
Now you need to form the sausage into links. Starting from the tied end, curl one hand around the sausage with your thumb beside where you want the twist to be. With your other hand, gently pinch the sausage skin closed, and twist the sausage to form a closure. Move on to the next pinch point and repeat the process but this time twist it the opposite way to what you did before. Continue forming links, alternating the direction of the twist each time.
When you are done, hang the sausages up to dry for an hour or two. These sausages need to be cooked before you can eat them.
Not an ingredient but pretty essential - a couple of metres of natural hog casing. You'll probably need to buy this online.
