Here's a couple more that have Texas roots you might be interested in.
First is Bigwheel's version of Smitty's BBQ Sauce
To a non reactive pot add this:
1 big jug of ketchup 46oz size
1 small bottle Lea n Perrins Wooster Sauce
2 T. chili powder
2 T. granulated onyawn
1 T. granulated garlic
1 small can grapefruit juice (Sacramento Brand if you can find it) BW once said any kind of juice but Smitty used grapefruit as a mystery ingredient.
2 t. cayenne (or however much suits your taste)
1 big ketchup jug full of water
Put it in the coolest part of the pit and let it chuckle away all day without a lid. Serve it on the side.
The next one was called Tom & Mary's Sauce when I found it somewhere or the other.
Think it was National BBQ News.
Saute 3/4 cup of onion and 2 or more cloves of garlic in oil of your choice. Pour off the oil (or not) and add these ingredients -
3/4 cup ketchup
3/4 cup water
1/3 cup vinegar (I used Apple cider vinegar)
3 tblsp sugar (I used turbinado)
3 tblsp Worchestershire sauce (go ahead - I can't spell either)
3 tblsp Mustard (plain old yellow)
2 tsp Salt (I used kosher)
1 tsp Pepper (Fresh ground)
1 8 oz can tomato sauce
Simmer until your happy with the thickness. This was the Taste of Texas to me as a child.
