Love the passion folks have for their preferences!!!!!
I used the can for years. It definitely helps make a moist chicken. But I have moved on from the chicken can to brining because I usually splatchcook or butterfly the chicken. I've found that brining and using the can doesn't seem to make any difference. I've done the chicken can and turkey cannon with everything from soft drinks to beers to cheap white wine. The white wine was my favorite and I often replace some of the water in the brine with the wine if I have some on hand.
I brine whole chickens, quarters, halves, split breasts, boneless breasts, bone-in or boneless thighs. If it's poultry, I brine it. Two reasons; first, I prefer the texture of brined poultry. The proteins are denatured and they are more consistent, firm, and the white meat less "stringy." Second, the moisture. A brined bird is much more forgiving than an unbrined bird and always moist, even if overcooked a little. I've overcooked brined boneless chicken breasts to an IT of 180F and they were still moist!
I typically brine for 18-24 hours. I found that you get the same denatured protein texture with less salt. I brine chicken in the refrigerator in an 8 quart stainless steel Dutch Oven because it fits in my refrigerator!
I like a sweeter brine so this is my recipe for poultry (I double for a whole turkey):
1/3 to 1/2 cup kosher salt (it dissolves easier). I use the 1/3 cup of salt if I'm using a salty rub to avoid an over-salty chicken.
1/2 cup molasses
1/2 cup dark brown sugar
6-10 cups water (enough to cover the chicken I'm brining)
Optional: 1 heaping tsp each of rosemary, thyme, oregano, basil, or you can skip the spices entirely. I've done both and can tell the difference. Just depends on my mood and what rub, spices, and sauces I intend to use when smoking, roasting, etc. If I'm going to sauce the chicken parts I typically leave the spices out so the rub and sauce are not overpowered by the spices. For a whole chicken or turkey I always add the spices.
Is the process above for everyone. Nah. But my family always raves about my chicken so it works for me. Love the raves, but I'm always open to new ideas.
