Welcome Jeremy. I am by no means an expert. Like others on here I copied the experienced sausage makers from various forums. I have made 10-12 batches of snack sticks. I grind chuck, add spices, cheese, and 1 tsp cure #1 per 5lbs meat. I use a lot of water to help the meat flow through the small tube.
I start in the morning, grind, mix, stuff and strait into the smoker. I know some may not agree with that, but I have never had a problem. If you do decide to cure overnight I would be inclined to stuff them and let them cure. I would think you would have to regrind before stuffing if you cure the whole mass of meat before stuffing. I don't like to regrind. I like to clean up one time if you know what I mean. Plus I don't like the texture after regrinding.
I like my sticks pretty dehydrated. I think you could leave them in the fridge, curing overnight without covering them. Just gives you a head start on drying. It would be best to hang them but who has room for that. Let one of the Pro's chime in on the curing, this is just how I do it. Good Luck, Marty
