Congrats to you and the Mrs on your little one
I have done the foil pack of sliced potatos with onion and butter and sesoned with S&P.
YOU CAN NOT COOK GREAT BBQ ON A CONSISTENT BASIS BY COOKING TO AN INTERNAL TEMPERATURE OR BY TIME ( XXX MIN PER LB) YOU MUST COOK BY FEEL! For Brisket and Pork Butts it must pass the poke test(probe like soft butter in the thickest part of the Flat) Ribs pass the Bend Test, These are the only reliable methods to ensure that your cook will be a success. There is one exception to these rules and that is Poultry which must achieve an internal temp of 170 deg in the thickest part of the thigh and 165 in the breast.
