This came to me pretty instantly, I've had it before and it's fun to make, delicious, and unusual (in Scotland).
The chile con carne is an amalgamation of a few recipes for Texas chile con carne that I've seen, with a few (but hopefully not too many!) unconventional steps. For the spice mix, you toast a mix of chiles (I used guajillo, ancho, chipotle, and árbol), then blend with onion, garlic, tomato purée, and a spice mix - I used Mexican oregano, smoked paprika, and toasted cumin seeds, coriander seeds, and black peppercorns.
After that, I heavily browned some beef brisket, cut into chunks, in a pan, working in batches. Then, I cooked off the spice paste, before adding the beef back in with homemade beef stock. I added apple cider vinegar, Worcestershire sauce, and the very traditional soy sauce, until it was where I liked it, and then simmered it for about 4 hours until the meat was very tender. Smoky, great level of heat, very filling and, to me at least, very Wild Western.
One thing I hadn't cooked before was cornbread, so I made the brown butter cornbread for Serious Eats (recipe here - they also have a chile con carne recipe that was one of the foundations for mine). It was really, really good, nice and fluffy inside with a crispy crust and a nutty flavour from the brown butter.
With both of the main Wild West elements together, I made guacamole and a vaguely Tex-Mex-inspired salad with corn, coriander, tomato, and bell pepper, some white onion, grated cheddar, coriander leaf, sour cream, and lime wedges. Very satisfied!
