How long should you boil a sausage?

I cook them on very low heat, and with no extra fat in the pan, since sausages are already so fatty. In order to stop them from sticking, I keep a spray bottle of water handy and just give them a spritz or two whenever they start to stick.

Another technique that I've heard of but never used is to just let them sit on minimum heat for ten minutes per side without trying to move them. Apparently, once one side is fully browned, it won't stick anymore.

Either way, you need low heat and a lot of patience.
