How to Make It
Preheat the oven to 325°. In a medium enameled cast-iron casserole, heat the canola oil until shimmering. Add the chopped onion and cook over moderate heat, stirring, until lightly browned, about 5 minutes. Add the minced ginger and the garlic and cook until fragrant, about 1 minute. Stir in the paprika, coriander and turmeric and cook for 30 seconds. Add the lamb cubes and cook, stirring, until the meat is no longer pink, about 5 minutes. Add the chicken stock, diced tomatoes and minced chiles to the casserole and simmer over moderate heat until barely tender, about 15 minutes.
Stir the julienned ginger, cilantro, jalapeño and garam masala into the casserole. Cover and bake for about 45 minutes, until the lamb is very tender. Serve the curry with basmati rice and naan.
