For the rice: Cook the ham and diced onions together in a sauce pan over low heat. When the onions start to soften, add 4 cups water and the butter and salt. Bring to boil, and then add the rice. Bring back to a boil, and then lower the heat and simmer until the rice is tender, 10 minutes. Drain and rinse twice to remove starch. Once completely drained, spread the rice into a single layer in a baking sheet and refrigerate.
For the red peas: Add the peas to a pot and cover with the chicken stock. Add the bay leaves, garlic, onions and country ham bone or fat to add pork flavor. Simmer until the peas are tender, and then drain, remove the vegetables and bay leaves and refrigerate.
For the demi-glace: Combine the ham, shallots, carrots, celery, onions, duck skin and fat and ham bone in a large sauce pot and cook until the fat has been rendered. Pour in the bourbon to deglaze and cook for about 1 minute. Bring to a boil, and then reduce to a simmer. Cook until reduced by half and coats the back of a spoon. Strain, season with salt and pepper and set aside to keep warm.
For the turnips: Place the turnips in a pot and cover with the chicken stock and add the butter. Boil until tender, and then slice off the bottoms to create a flat surface.
For cooking the duck: Heat a cast-iron skillet until smoking hot. Sear each duck breasts for about 2 minutes per side. Set aside to rest for at least 2 minutes. Combine 1 teaspoon duck fat with 2 ounces red peas, 2 ounces rice, 1 teaspoon salt, 1 teaspoon pepper and 1 teaspoon chopped scallions in a pan and cook over medium-low heat to warm through.
