My first and only brisket I've done in my uds was the first tiny step. It was a 6.5# flat, choice from costco. Very basic cook. Rubbed with ground pepper, fat side down, no turnie over.. no foil..., no lift lid. It had a great smoke ring, great bark and the flavor was out standing.......but it was a little dry. Next time?
This is what makes it fun!
