In a bowl, combine the buttermilk with 1 tablespoon of the Essence. Add the oysters and marinate for 20 minutes.
Combine the masa harina and flour with the remaining Essence in a shallow dish.
In a deep-fryer or a medium, heavy pot with high sides, heat the oil to 360 degrees F.
Dredge the oysters in the flour mixture and shake the pieces in a strainer to remove any excess. Carefully add to the hot oil in batches, and cook, turning occasionally, until golden on all sides, 2 to 3 minutes. Remove the oysters with a slotted spoon, drain on paper towels, and serve immediately.
