Step 1 of 4
Make the adobo
Soften the seeded guajillo chiles in hot water, then drain and let them cool before blending. Blend with achiote paste, orange juice, lime juice, garlic and salt. Coat the thin pork slices and marinate covered in the refrigerator for at least 3 hours. Keep raw-meat utensils away from garnishes; discard used marinade.
