Iāll echo other people about brining and not low and slow.
I do a DRY brine for at least one hour in the fridge and up to 24h. I did that 2 years ago on a oven roasted turkey and never went back to wet brine. Works on chicken in SF too.
You can do low for a short time, if you want a lot of smoke flavor. Iāve used smokeboost only once on chicken, for 15 minutes on drumsticks, and it worked quite well.
Otherwise, I do 350F until meat is at 135-145F, and the ramp to 450F until cooked.
Skinless and fat-trimmed pieces donāt need a tray under, so I prefer not to use one.
With skin and fat on I do use a dry tray as I am not into reducing stuff into sauce, but I am into cutting potato slices and having steaming hot fat falls on them. Picked that from a food truck in the Bay Area.
I used to do add water in my tray in the kettle, but I feel thereās just way more air flow in the SF, so I started spritzing water, beer, or juice, during low and slow for red meat, or fish. I havenāt tried with chicken but that could work. Maybe next time I do a whole or parched chicken.
