Combine the corn, tomatoes, onions, jalapenos, cilantro, lime juice, and lemon juice. Mix well. Season the salsa with salt and pepper. Set the salsa aside. In a saucepan, combine the horseradish, shallots, garlic, mustard, white pepper and cream. Season with salt and pepper. Bring the liquid to a boil, whisking gently. Reduce the heat and simmer, stirring occasionally, until the sauce is thick enough to coat the back of a spoon, for about 12 minutes. Remove from the heat and keep warm.
In a small bowl, season the flour with Essence. In another bowl, season the masa with Essence. In a third bowl, beat the eggs with the milk. Season the oysters with Essence. Dredge the oysters in the seasoned flour. Dip the oysters in the egg wash, letting the excess drip off. Dredge the oysters in the seasoned masa, coating each side completely. In a large saute pan, heat the olive oil. When the oil is hot, but not smoking, carefully lay the oysters in the hot oil. Pan-fry the oysters for about 1 1/2 minutes on each side or until golden brown. Remove the oysters form the pan and drain on a paper-lined plate. Season the oysters with Essence. Serve the oysters with the horseradish cream and salsa.
