i am sure this has been discussed a million and one times on the forum i just missed it so i will try again
can anyone help with brisket injection? i make my own and it is ok not over the top
what is everyone using or what is a good brisket injection to use?
i have been using some beer, homemade french onion soup, beef stock, and a little bit of the rub steeped in the soup
it just does not have that strong of a flavor, almost no flavor at all...weird
