In a small, heavy saucepan, place the potatoes, 1/2 teaspoon of the salt and enough water to cover by 1 inch. Bring to a boil. Reduce the heat to medium-low and simmer and until the potatoes are fork tender, about 15 minutes. Remove from the heat and drain in a colander.
Return the potatoes to the saucepan. Add the cream, butter and the remaining 1/4 teaspoon salt. With the heat on medium-low, mash until well blended, about 2 minutes. Remove from the heat and let cool.
In a medium sauté pan heat the olive oil over medium-high heat. Add the onions and peppers, and sauté until soft, about 3 minutes. Add the garlic and sauté for 1 minute. Remove the pan from the heat and let cool.
In a bowl, combine the mashed potatoes, cooked vegetables, crab meat, green onions, grated cheese, parsley, Creole mustard, 2 tablespoons lemon juice, 2 teaspoons Essence, and remaining 1/2 teaspoon salt. Mix to incorporate.
In a shallow bowl, season the flour with 1 teaspoon of the Essence. In another bowl, whisk the remaining egg with the water. In a third bowl, combine the bread crumbs and 1 teaspoon of the Essence.
Divide the crab-potato mixture into 1/3-cup portions, and form into patties about 1-inch thick. Dredge both sides of each cake in the seasoned flour, dip in the egg wash, letting the excess drip off, then dredge in the seasoned bread crumbs, covering both sides completely. Set aside on a baking sheet to bread the remaining mixture.
In a large, heavy skillet, heat 2 tablespoons olive oil over high heat. Carefully add the cakes to the pan being careful not to overcrowd, and cook until golden brown, 3 to 4 minutes per side.
Remove the cakes from the pan and drain on a paper-lined plate. Season the cakes with the remaining teaspoon of Essence and serve immediately with Remoulade sauce.
