I think Tejas style used to be a lot simpler. I haven't been in a long time, but the times I've been (and lived there briefly) I ate more than my fair share.
I see recipes calling for everything from soup to nuts, and that's ok, but I remember a little hole in the wall Q place (not one in particular, but in general) that would sell a plate of brisket, sausage, and Wonder Bread with maybe another carb and the sausage was always simple. Beefy, peppery, maybe some mustard seeds and a dash of garlic. Now, to be fair, they were almost always full of Latinos including the pitmasters.... Not a Czech in sight ;)
Now in the last 20 years with the explosion of Food TV and FLAVORTOWN NYUCK NYUCK NYUCK and the famous places all divulging little pieces of their secret array of herbs and spices, it's just more than what it once was. But - as I've said many a time on here, I'm a purist. Beef tastes mighty good with just salt, pepper, and smoke. Pork is another ballgame. I throw lots of herbs and spices at it lol.
I've got some beef links drying right now - and it's mighty simple. I hope it tastes at least somewhat like I remember.
