Hi everyone, Andrew Hayes here. (professional chef, Brisbane Australia) FEC240(2022)
Hello and thank you for this wonderful forum. i have been looking for an overnight brisket method that was suitable for our establishment(lunch times only). and i couldn't find a suitable method on the forum(one that starts their meat just after lunch 3pm ready for next lunch service), so i have spent the last 5 months getting this right and ill post it here.
This is a wrap, or no wrap method and the oven start time will be anytime between 2pm and 4pm with the brisket ready for 11am lunch service the next day. our chefs start at 7am and work till 3/4pm.
(both wrap and no wrap work, but wrapping works a little better with less shrinkage and the wrapping isnt untill 5-7am the next morning)
this is tried and tested and works well for those businesses who cant start their brisket at 9pm or 10pm at night.
Note: the pork collar butt(no bone like the boston butt) works but gets a little too much skin if not wrapped in the morning.
Here goes:
try it and if you have any other thoughts or additions on timings and temperature that you know please add comments
