How to Make It
In a large enameled cast-iron casserole, heat the olive oil. Add the onions and cook over moderate heat, stirring occasionally, until they are softened and just starting to brown, about 8 minutes. Add the garlic, ginger, berbere, nigella seeds, cardamom and a generous pinch each of salt and black pepper and cook until fragrant and deeply colored, about 10 minutes.
Add the red lentils with 8 cups of water to the casserole and bring to a boil. Cover and cook over moderately low heat, stirring occasionally, until the lentils have cooked downand thickened, 25 minutes. Season the lentils with salt and pepper. Ladle the lentils into bowls, sprinkle with berbere and serve.
