Here's why this dish deserves a permanent spot in your weekly rotation. The combination of aromatic spices and deeply flavored chiles creates something truly special. You'll start by combining ground cumin, coriander seeds, dried oregano, kosher salt, and freshly cracked black pepper in a small bowl. Generously coat the entire pork shoulder with this seasoning blend, then let it rest while you prepare the remaining ingredients. Next, heat a heavy skillet over medium warmth without any oil. Add the dried guajillo peppers and cook them until they release their aroma, about a minute or two. Immediately transfer the toasted chiles into your slow cooker pot.
