I would say if you already have added the 10% suit you have a 90% lean meat may just get some pork butt and grind it in with the burger. If you want to give it a try shoot me an email with your contact info next Monday and I will give you a discount on the seasonings and in return just come back on the blog and let us all know how you enjoyed it. (Make sure when you buy the pork from your local grocery store to ask the butcher if their pork is pumped with saline solution. If so buy it else where pumped pork is not as appealing and a bit more salty when made into sausage. My e-mail is [email protected]
