Cooking : Authentic Bangladeshi Beef Curry

Ingredients
3 tablespoons olive oil
1 onion, chopped
6 cloves garlic, minced
5 green chile peppers, finely sliced
1 teaspoon fresh ginger root - peeled, sliced, and ground into a paste
3 cardamom pods
2 whole cloves
1 1/2 cinnamon sticks
1 teaspoon ground cumin
1 teaspoon ground coriander
1 teaspoon ground turmeric
1 teaspoon garlic powder
1 teaspoon cayenne pepper
1 cup water
2 pounds boneless beef chuck, cut into 1-1/2-inch pieces

Directions
Heat the oil in a skillet over medium heat. Add the onion; cook and stir until the onion has softened and turned translucent, about 5 minutes. Reduce heat to medium-low, and continue cooking and stirring until the onion is very tender and dark brown, 15 to 20 minutes more.
Stir in the garlic, green chiles, ginger paste, cardamom pods, cloves, and cinnamon sticks. Cook and stir for an additional 3 to 5 minutes, until the garlic begins to brown.
Stir the cumin, coriander, turmeric, garlic powder, cayenne pepper, and water into the onions. Simmer until most of the water has evaporated and the mixture has thickened.
Stir in the beef chuck and cook on medium-low heat, stirring occasionally, until the meat is cooked through and tender, about 1 to 1 1/2 hours.
