I think my first introduction to hot sauce was in a frozen TV dinner - probably Swanson’s Mexican dinner, back in the 1970s. It would have enchilada and tamale in sauce in the main part; refried beans and rice in the small areas up top; and in the middle, this wonderful hot sauce. I had never tasted anything like that at the time - I was raised on pretty simple, down-home cooking. I suspect that the TB hot sauce is very like the sauce in that TV dinner was.

You’re right. That Taco Bell hot sauce IS very good.
As usual, I always like to amp up a product or a recipe.
I add a smidgen of raspberry flavoring to the hot sauce——the taste is bumped up to ethereal.
Use any type raspberry flavored powder....
I’ve even used Lipton Raspberry tea powder with great success.
