What do Texans call slow cooked beef served with a hot spicy sauce?

There isn't one specific name for slow-cooked beef served with a hot spicy sauce that is unique to Texas. However, there are several terms that could apply depending on the specific dish:

* Brisket: This is the most likely answer if the beef is slow-smoked and served with a traditional Texas barbecue sauce, which often has a smoky, sweet, and tangy flavor profile with some heat.

* Chili: If the beef is stewed with beans and other ingredients, and the sauce is more of a chili base, then it could be called Texas chili.

* Barbecue: This is a general term, but in Texas, it often refers to slow-smoked meats, including brisket. If the sauce is spicy, it could be called spicy barbecue.

* Spicy Beef: This is a more general term and could apply to various preparations, including stews, braised dishes, or even slow-cooked beef with a spicy marinade.

The best way to find out what a specific Texan calls this dish is to ask them! There's a lot of regional variation in food traditions and vocabulary, so what one person calls it might be different from what another person calls it.
