Step 1 Heat the ghee in a large kadai or cast-iron wok over high heat. As the ghee warms, add all the spices at once and stir them through. Step 2 Before the spices reach the point where they look like they might burn, add the pumpkin. Step 3 Cook until the pumpkin browns on one side, taking care not to move it too much. Step 4 Turn carefully and cook as before until the pumpkin is completely browned on all sides and cooked through.
