How is your timing on ribs?
Many folks think cooking your butt and ribs at 250*,won't be distinguishable.
Are you timing this to feed company at a specific time?
If not,you can experiment and learn.
One option could still be ,have the cooker ready to go and pop the butt in at 6 AM.
You could already have the butt at room temp,and the smokette preheated-just drop the wood in and load the meat.
Have your ribs prepped,ready to go in about noon.Room temp.
You can pull the butt out at 3PM,foil it and the ribs,put all back in.
Then you have to play by ear.
If your ribs are done,around4-5 pm,and the butt isn't,have your kitchen oven preheated to about 300*.
Pop the foiled butt in,and it will finish quick.
If the butt was already close ,crank the smokette all the way up,and take the butt to 195*
Foil and let rest,as long as you have time.
Is this the absolute best? Maybe not,but it should be close on the butt.
Take good notes all the way through,and make adjustments to hone your act the next time.
It should still give you time to finish the ribs,for an early dinner.
I often toss in a couple lbs of presmoked sausage,they will finish in an hour.
Cut in one inch pieces,toothpick,serve with sauce,to keep the impatient diners at bay-while they drink you cold drinks.
Now,before the flaming starts,I'm not advocating to cook a first cook in foil,without learning the cooker FIRST.
Yes,I am saying that foil can speed a cook,and make the cooker get the job done for you.
