To use it in sausages you've really got to boil it well until it's very soft or it can end up gristley like FB said, I've tried it a couple of times and I'm not too impressed. It does wonders for an emulsified sausage though.
Most of mine ends up as Pork Scratchings these days:
Slash, then rub generously with salt and a little pepper. Roast in an oven at 140C for 1�-2 hours, draining the rendered fat every 30 mins or so. Then increase the oven temp to 200C and after about � an hour they should have puffed up and crisped.
Take out, drain on some kitcken paper, allow to cool, break along the slashes, sit back with a beer and watch everyone wolf them down.
