Friends who live in Mexico shared this dish with me years ago. They cooked the roast in a clay pot in a slow oven, but I found the recipe works well in a slow cooker. The leftovers make excellent burritos and tacos. —Chuck Allen, Dana Point, California
In a large skillet, heat oil over medium-high heat. Cook the onions, carrots and jalapenos until tender, 2-3 minutes. Add garlic; cook 1 minute longer. Transfer to a 5-qt. slow cooker; add water and broth.
In a small bowl, combine the coriander, salt, cumin, oregano and pepper; rub over roast. Cut roast in half; place in the slow cooker. Cover and cook on low until meat is tender, 8-9 hours.
Transfer roast and vegetables to a serving platter; keep warm. Strain cooking juices and skim fat. Pour into a small saucepan. Bring to a boil; cook until liquid is reduced to about 1 cup. Serve with roast and vegetables.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
