In a large pot over medium heat, add the butter and ham. Once the ham starts to get a little color, add the onion, peppers and garlic, cooking until softened. Add the flour and stir until incorporated.
Next add the potatoes, corn, salt and Biscayne Citrus Rub, mixing well. Add the three cups of chicken stock and stir. The mixture should start to thicken. Stir in heavy cream.
Cover pot and set on low. Stir occasionally. Simmer for 12-15 minutes or until potatoes are tender.Serve hot. Garnish with chopped cilantro, lime wedge and green onion.
