Drain the casing after rinsing well on the insides under a running tap. Place the casing over one end of the filling horn on the mincing machine. Carefully push all of the casings on leaving about 7-8cm over to hang down. Tie a knot in this hanging piece so that the meat will not fall out.
You then feed the wors mixture into the casing horn while your assistant holds the casings, guiding the filling along the tube.
Feed the mixture into the mincer a little at a time, (depending on what you are using). At the same time, secure the casing with a gentle pressure of one hand on the horn to control the unrolling of the casing as its filled.
Mold the mince with your hand to make it uniformly thick.
Don’t pack the casing too full, or the boerewors will burst while cooking but try to avoid air bubbles. If there are air bubbles, pop them open and continue.
After the casing has been filled, remove it – still attached to the horn – from the mincing machine.
Push any remaining filling into the casing and tie a knot in the end. You can also just turn it tightly. It is now ready to be cooked.
