Preparation Simmer lentils with parsley, bay leaf, broth, and water in a 4-quart saucepan, uncovered, until tender, 30 to 40 minutes. While lentils are cooking, coarsely grind peppercorns with cumin using a mortar and pestle or an electric coffee/spice grinder. Heat 1 tablespoon oil in a 4-quart heavy saucepan over moderate heat until hot but not smoking, then cook bell pepper, stirring, until golden, about 5 minutes. Add spices and cook, stirring, 1 minute. Add carrot, celery, onion, garlic, and remaining 3 tablespoons oil and cook, stirring, until carrot is tender, about 8 minutes. Stir in lentil mixture and discard bay leaf. Purée 1 cup soup in a blender until smooth (use caution when blending hot liquids). Stir purée into remaining soup and reheat over moderate heat, stirring. Season soup with salt and pepper. If soup seems too thick, thin with water to desired consistency. Cooks' note:· Soup can be made 1 day ahead and cooled, uncovered, then chilled, covered.
