I use alot of these , but I use them on lean cuts like pork loin , eye round beef .Most any of the Tony C's injectable marinades are great, inexpensive and readily available.
Works for this too , just read the label so you are aware of the sodium levels . I don't add salt when using these , except for the praline ham injection .
Most of these injections contain sodium phosphates which is why they work so well .
The praline ham injection does not contain phosphates or any salt .
Used alone on a fresh piece of meat will give poor results .
Also , Pay attention to this from post 5 .
If you are going to inject salt in any of that stuff... Weigh out 1.75% salt, based on the weight of the butt, dissolve the salt in the injectable stuff... I would inject 10% the weight of the butt in injectables..
