This North African-style tagine trims and briefly brines lamb kidneys to mellow their flavor before braising them in a spiced tomato and onion sauce. Cumin, paprika, and preserved lemon give the sauce a tangy, earthy depth, making it a hearty dish served with crusty bread for sopping up the juices.
Ingredients
- 1 1/2 pounds lamb kidneys, trimmed of fat and membrane, halved
- 2 tablespoons white vinegar
- 3 tablespoons olive oil
- 1 large onion, finely chopped
- 4 cloves garlic, minced
- 1 tablespoon tomato paste
- 1 cup diced tomatoes
- 1 teaspoon ground cumin
- 1 teaspoon sweet paprika
- 1/2 teaspoon ground coriander
- 1/4 teaspoon cayenne pepper
- 1/2 teaspoon ground ginger
- 1 preserved lemon, pulp removed, rind chopped
- 1 cup water
- 1/4 cup fresh cilantro, chopped
- 2 tablespoons fresh parsley, chopped
- 1 teaspoon salt
- 1/4 teaspoon black pepper
Method
-
Trim the kidneys of any remaining fat and silverskin, halve lengthwise, and cut out the white core. Place in a bowl, cover with cold water and the vinegar, and soak for 15 minutes to mellow their flavor.
-
Drain the kidneys and rinse thoroughly under cold water, then pat dry with paper towels.
-
Heat the olive oil in a 9-inch skillet or tagine base over medium heat. Add the onion and cook, stirring occasionally, until softened and translucent, 5 to 7 minutes.
-
Add the garlic and tomato paste and cook, stirring constantly, until fragrant and the paste darkens slightly, about 1 minute.
-
Stir in the diced tomatoes, cumin, paprika, coriander, cayenne, and ginger. Cook, stirring, until the tomatoes break down slightly, about 3 minutes.
-
Add the kidneys to the skillet and stir to coat in the sauce. Cook for 2 minutes to sear the surfaces.
-
Pour in the water and add the preserved lemon rind, salt, and black pepper. Stir to combine, bring to a simmer, then reduce heat to low, cover, and simmer gently until the kidneys are tender, 35 to 40 minutes, stirring occasionally.
-
Uncover and simmer an additional 5 minutes to thicken the sauce slightly, adjusting salt to taste.
-
Stir in the cilantro and parsley, then remove from heat. Serve hot with crusty bread.
