How to Make It
In a large bowl, combine 2 tablespoons of the canola oil with the cumin, crushed red pepper, soy sauce, cornstarch, sesame oil, sugar and 1 teaspoon each of salt and pepper. Add the lamb and onion and turn to coat. Let stand for 10 minutes.
Heat a large cast-iron skillet until very hot. Add the remaining 1 tablespoon of canola oil and swirl to coat. Add the lamb and onion and cook, stirring occasionally, until browned, about 10 minutes. Stir in the scallions and cilantro. Add the broth and cook, stirring and scraping up any bits stuck to the bottom of the skillet, until the broth is evaporated, about 2 minutes. Serve with rice.
