Steps
Before you start

- Ensure you have a large zip-top freezer bag or non-reactive container for marinating
Toast the chiles
- Heat a small skillet or comal over medium heat.
- Place the seeded and stemmed guajillo chiles in the dry pan and toast for 1–2 minutes per side, pressing gently with a spatula until fragrant and lightly darkened.
- Do not scorch them.
- Transfer to a bowl.

Ready when: Chiles are fragrant and slightly darker, with a few lighter spots
Tip: Toasting deepens the chile flavor; don't let them burn or the marinade will taste bitter
Soak and soften chiles
- Pour 1 cup (240 ml) of hot water over the toasted chiles and let them soak for 15–20 minutes until completely soft and pliable.
- The soaking liquid will darken as the chiles rehydrate.

Tip: Don't skip the soaking step—it makes the marinade smooth and helps extract maximum flavor

- Transfer the softened chiles and their soaking liquid to a blender or food processor.
- Add the lime juice, orange juice, peeled garlic cloves, cumin, Mexican oregano, bay leaves, olive oil, apple cider vinegar, salt, black pepper, and cinnamon.
- Blend on high speed for 2–3 minutes until completely smooth, with no chile flecks remaining.

- Pour the marinade into a gallon-size zip-top freezer bag or non-reactive container.
- Cut pork shoulder into 4–5 pound chunks (roughly 3–4 inch pieces) and add to the marinade.
- Massage or shake the bag to coat all surfaces.
- Refrigerate for at least 8 hours, preferably 12–24 hours, before braising the carnitas in a low oven or slow cooker at 300°F (150°C) for 3–4 hours until the meat shreds easily with a fork.

Good to know
Tips
- Use Mexican oregano rather than Italian oregano—it has a more subtle, citrusy character that suits this marinade
- For the deepest flavor, marinate the pork for a full 24 hours; even 8 hours delivers excellent results
- Toast the dried chiles dry in the pan without oil—this blooms their flavor and creates a richer base
- Reserve the entire marinade to use as your braising liquid; it becomes a silky sauce as the pork cooks
Make ahead
Prepare the marinade up to 2 days ahead; store in an airtight container in the refrigerator. Once the pork is added, marinate for at least 8 hours but no more than 24 hours for best flavor.
Storage & reheating
Unused marinade (without meat) keeps in an airtight container in the refrigerator for up to 5 days, or frozen for up to 3 months. Once the pork is marinated and braised into carnitas, store in an airtight container in the refrigerator for up to 4 days. Reheat gently in a low oven (300°F/150°C) for 15–20 minutes until warmed through.
Substitutions
- dried guajillo chiles → ancho or pasilla chiles. These offer a slightly deeper, earthier flavor; use the same quantity and prepare identically
- mexican_oregano → dried oregano (Mediterranean). Mediterranean oregano is more peppery; use only ¾ teaspoon to avoid overpowering the marinade
- fresh orange juice → fresh grapefruit juice or additional lime juice. Grapefruit adds subtle bitterness; lime alone will intensify the citrus note
- apple cider vinegar → white vinegar or fresh lime juice. White vinegar is sharper; lime juice will soften the acidity but adjust to taste
