Pakistani Lentil Curry - cooking recipe

Ingredients

3/4 cup dry brown lentils
1/4 cup dry red lentils
4 cups water
5 whole garlic cloves
3/4 teaspoon salt
1/2 teaspoon ground coriander
1/2 teaspoon cayenne pepper, or to taste
1/4 teaspoon ground turmeric
2 tablespoons clarified butter
1/4 onion, sliced
1 teaspoon ground cumin
1/8 cup milk (optional)
1 tablespoon minced fresh cilantro

Preparation

Soak brown and red lentils in ample cool water for 1 hour to overnight. Drain and rinse.
Place drained lentils into a large saucepan or Dutch oven. Pour in the water, then add garlic, salt, coriander, cayenne, and turmeric. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until the lentils are tender, about 30 minutes.
While the lentils cook, melt the clarified butter in a skillet over medium heat. Stir in the onions, and cook, stirring often, until they turn golden brown. Stir in the cumin, and cook until fragrant, about 1 minute.
Stir the onions and milk into the lentils; cook for another 6 to 8 minutes. Sprinkle with cilantro to serve.
