I think they put the ends in their beans.
And I'll tell you what - BBQ snobs be damned, HEB puts out some fine brisket. I get worn out with California cowboy wannabes coming to Texas, sitting around at brunch arguing about BBQ and breakfast tacos like they know what they're talking about because they saw it on some TV show. There is no such thing as bad BBQ in Texas and there is no such thing as a bad breakfast taco in a Mexican diner.
These people stand in line at Franklin's in Austin because the PR people tell them to, not because Franklin's BBQ is superior to anywhere else. I'll bet in a blind taste test between Franklin's and HEB brisket, they'd be hard pressed to choose which one is better.
