In a mixing bowl, combine ground beef, apple cider vinegar, chili powder, smoked paprika, cumin, garlic powder, oregano, cinnamon, salt, black pepper, and cayenne (if using).
Mix thoroughly until the seasonings are evenly distributed. Cover and marinate in the refrigerator for at least 1 hour (or overnight for deeper flavor).
Heat a skillet over medium-high heat. Add the seasoned beef chorizo mixture and cook, breaking it up with a spatula, until fully cooked and slightly crispy, about 10-15 minutes.
Serve warm in tacos, burritos, eggs, or your favorite dishes.
