1Season the lamb with sea salt. In a heavy-bottomed braising pan, heat the oil. Brown lamb shanks deeply on all sides, turning occasionally. Work in batches to avoid over-crowding the pan. Once the lamb is caramelized on all sides, set aside.
2Blend the onions, ginger, garlic and jalapeños until a smooth consistency is reached. In a separate container, mix the coriander, curry powder and cinnamon. Set aside.
3Using the same pan over medium heat, add the onion-garlic paste; allow to cook just until golden, 1 to 2 minutes. Stir in spice mixture; simmer for an additional 20 seconds. Add the water or lamb stock. Increase heat to medium-high, bringing mixture to a boil; reduce to a simmer. Temper the yogurt into the braising liquid by gradually whisking it in until combined with the sauce.
4Return lamb shanks to the pan; cover and simmer very gently until the lamb is fork-tender, about 2 hours. Check and stir frequently so as not to burn the pan. Add the yucca and sweet potatoes during the last 15 minutes and cook until tender.
5Taste and adjust the seasonings with salt. Garnish with fresh mint.
