I did my first brisket today. Got a 10 lb USDA choice, untrimmed.
I rubbed it with some homemade steak rub and a bit of montreal steak seasoning the day before.
Using the minion method, I had the temp between 220-250 for 8 hrs and it was 190 internal temp. I left it on for 1 more hr, wrapped it in foil and a towel and stuck it in a cooler for 1 more hr.
It came out perfect.
Kudos to all you fine folks here... reading your advice and directions my 2nd smoke ever (and first brisket) was a resounding success.
