1. Preheat oven to 220°C on broil / top grill setting. Line a baking tray with crumpled foil to stabilise the oysters, then arrange the oysters upright.
2. Chop both types of bacon into small pieces.
3. In a small bowl, mix all the sauce ingredients until well combined. Spoon 1 teaspoon of sauce over each oyster.
4. Top with chopped bacon, gently pressing them into the oyster shell.
5. Place the tray on the top oven rack and grill for 5–6 minutes, until bacon is crispy and cooked through.
6. Serve immediately with parsley and a squeeze of lemon, if desired.
