Measure out your dry ingredients in to a large bin or container with a lid.
Next, add in some water and use a whisk to mix the ingredients. The seasonings won't dissolve all the way.
Next, add in your cornish game hens and ensure they are fully submerged in the brine.
Either store in the fridge or add ice to the container.
Prep your smoker; I always start by turning it on and placing it in my chips.
While waiting for the smoke to start rolling, spray your racks with non-stick spray or rub them with olive oil.
Remove your cornish game hens from your brine and place them onto your smoker racks.
Once you have smoke rolling for your smoker, place your chickens in your smoker.
I kept my smoker at 200-225 (way easier in colder weather); I like to cook meat low and slow for flavor.
Keep an eye on your smoker; smoke the chickens for a couple of hours.
Use a meat thermometer to verify they are 165 degrees; cook for temperature, not for time.
Remove and serve!
