Tried your Recipe tdj_tx, but I reduced the recipe by 50%, so as not to make too big a batch.
Just in case.
I was surprised, that it thickened up as well as it did, considering the amount of water.
Of course, I have never had a Texas Hot before, so not sure what to expect. I followed the recipe to a T, accept the reduction in batch size.It turned out very well.
It was surprisingly, very tasty.
Here is a pot of ready to eat, Texas Hot Sauce.
I even diced the onions, very small, and used regular yellow mustard.
The recipe is a keeper but I believe it can be improved on to give it a little more flavor and body.
Have you tried beef stock or chicken stock in place of water?
Mmmm! Gotta go eat.
