Tips: Because chile peppers contain volatile oils that can burn your skin and eyes, avoid direct contact with them as much as possible. When working with chile peppers, wear plastic or rubber gloves. If your bare hands do touch the peppers, wash your hands and nails well with soap and warm water.
To simplify, use 3/4 teaspoon ground cumin in place of the 1 teaspoon cumin seeds. Add ground cumin to the marinade with the salt, skipping the toasting step.
