Make Ahead Tip: To make ahead: Marinate the pork (Step 1) in the refrigerator for up to 8 hours.
Chipotle chiles in adobo sauce are smoked jalapenos packed in a flavorful sauce. Look for the small cans with the Mexican foods in large supermarkets. Once opened, they'll keep up to 2 weeks in the refrigerator or 6 months in the freezer.
One pork tenderloin typically weighs about 1 pound, enough for 4 servings. You can marinate a whole pound in the same amount of marinade used to marinate the 8 ounces in this recipe and have enough cooked tenderloin for 2 dinners (for 2 people). Or freeze half for up to 3 months.
To warm tortillas, wrap in foil and bake at 300°F until steaming, about 5 minutes. Or wrap in barely damp paper towels and microwave on High for 30 to 45 seconds.
