Serve with warm naan or a crusty bread of your choice, or on a bed of fragrant jasmine rice.

Soak the chiles in the vinegar for 15 minutes. Add the garlic and ginger to the chiles and, using a blender or food processor, blend into a paste. Scrape the mixture into a small bowl.

Add the cumin, coriander and cinnamon to the mixture; mix thoroughly. Add the crab pieces and stir to coat them well. Cover and refrigerate for from 30 minutes to 1 hour.

Heat the oil in a large Dutch oven over medium-high heat. When the oil is hot, add the crab and brown on all sides. Add the salt, water and sugar to the pan. Bring to a boil. Cover, reduce heat and simmer for 12 to 15 minutes, stirring occasionally, until the crab is cooked through and the flavors have blended. Garnish with cilantro.

Serves 2.
