Briny oysters are the ideal food for a delicious brunch, dinner, or special occasion when they are topped with a rich cream, garlic, spinach, and cheese sauce and baked till golden and bubbling.
Set shelf one level above the oven's center and heat the oven to 180°C (355°F).
Eschallots and garlic are added to a medium frypan with moderately melted butter and are cooked until tender (2-3 minutes)
Add the wine, cream, 2 tablespoons of the cheddar, salt, and pepper. Gently boil for 5 minutes, or until the sauce has slightly thickened and decreased.
On a platter just big enough to accommodate the oysters, sprinkle rock salt.
Place the oysters on the tray, using salt to balance each shell evenly. Spoon sauce and spinach over each oyster, finishing with a pinch of cheese. Bake for 20 minutes, or until the tops are slightly browned and bubbling.
