Smoke powder? Well, that gives you another piece of equipment to ask for next Christmas or for your anniversary. Honestly, your jerky will be fine with the smoke powder, but you’ll have to take some C-R-A-P from guys like me. Ha!
Also, I have a Cuisinart mixer that’s a Kitchen Aid clone. Bowl is plenty full with 5# of meat/fat/water, but it does a dandy job. I run mine on setting 1 (slowest), using the flat paddle rather than the dough hook. Takes me 10-11 minutes to get the stickiness I like.
Lube up that stuffer and tube because it takes all kinds of pressure to force that meat into a 19mm casing, which is what I use also.
