Reading this thread the other day got me going on something I've never made before. 
Luckily, the local supermarket chain has pork shoulder on sale for $.99 lb so I picked one up after work and got it going. 
I discovered that I need a larger heavy bottom pot. I've roasted pork shoulder before but rarely boiled one. I pretty much followed the simple recipe this time and used canned enchilada sauce. Sauce from scratch will happen next time. 
Everything turned out really well and it earned a thumbs-up from my girlfriend, who was pleased it wasn't too spicy for her to eat. This morning I even had some under my eggs for breakfast. 
Thanks for the idea!
