Bring a saucepan of water to a boil. Reduce the heat and add the raw sausages. Poach at a gentle simmer for 10 minutes. Remove the sausages from the water and allow them to cool slightly.
Put some flavourless oil in a frying pan and place over a medium-high heat.
Pat the sausages dry with kitchen paper. Then, add them to the frying pan. Fry until all sides of the sausage is coloured to your liking.
Remove from the frying pan and allow excess grease to drain away.
