Mix the ketchup and Worcestershire sauce together to make the “Kilpatrick” sauce and keep it aside.
Cover an oven tray with a bed of coarse salt and put the oysters on it. Divide the bacon over the oysters and top them with a little bit of Kilpatrick sauce (about 1 tsp per oyster).
Grill in the oven until the bacon is cooked (about 10 minutes)
Serve with the extra Kilpatrick sauce and lemon wedges.
