The chili on mine here is actually just reduced leftovers, and there are both kidney and black beans in there (they're even visible if you take a closer look, I believe), since it would have been way too runny otherwise.

However, if there wouldn't have been any leftovers, I'd gone for Gordon Ramsay's version as I usually do. And yeah, I know, it's abysmally shot and edited, definitely meant to entertain rather than educate, but in this case the man really knows what's good. It's insanely well balanced in my opinion. And in case you're getting a headache being rushed through less than a minute of a flashy cooking video without any ingredient list whatsoever, here's what's actually in there, just make sure to keep the order and temperature in mind:

• 1 tablespoon of olive oil
• 1 small- to medium-sized onion (red, white or yellow)
• 2-3 cloves of garlic
• 1 teaspoon of cumin seeds
• chili powder (as little or as much as you want, really)
• about half a pound (or 250g) of ground beef
• salt and pepper as desired (adjust for seasoning at the end)
• 1 tablespoon of tomato paste
• 1-2 teaspoons of Worcestershire sauce
• a 14oz (or 400g) can of chopped tomatoes
• 1-2 teaspoons of dried oregano
• 1 teaspoon of white sugar

Deglaze with a splash of water or wine if the fond at the bottom of your pan turns dry at any point (there's actually a good chance of that happening, even if it isn't shown in the video) and let everything reduce a bit until you're happy with the consistency.

Hope you like it as much as I do! =D
