–International Dutch Oven Society
Arrange the briquettes in ring patterns, with eight underneath and 16 to be placed on the top of the Dutch oven. Cover the potatoes with water in the Dutch oven, and boil until soft enough to mash. While potatoes are boiling, in a medium mixing bowl, mash the sprouts, cilantro, mango powder, salt, pepper, chiles, and butter to form a paste. Mash or rice the potatoes. Stir the paste into the mashed potatoes.
