Add the garlic, bay leaves, cayenne, Essense and sausage. Season with salt and pepper. Add the stock and mix until thoroughly incorporated. Bring the liquid up to a boil and reduce the heat to low.

Season with salt and pepper if needed. Ladle the gumbo in a boil and top with rice. Garnish with green onions and Essense.
