I was about 10 minutes into trying to stuff my first batch of sausage with my grinder attachment. I put the rest of the meat in the fridge, drove to gander mountain, and bought a stuffer. Worth every penny, and then some.
When I use jalapenos I roast them first, strip off the skin, then chop. It mellows them, and gets most of the moisture out too. If you really like the flavor but don't want to overpower, this may be an option for you.
