Ingredients:
- 4 large Russet or Maris Piper Potatoes (approx. 1.2 kg total)
- 2 Tbsp Extra Virgin Olive Oil (or duck/goose fat)
- 1 tsp Flaky Sea Salt (such as Maldon)
- 1/2 tsp Freshly Ground Black Pepper
- 2 Tbsp Unsalted Butter (optional, for serving)
Instructions:
- Preheat the Oven: Set your oven to a blistering 425°F (220°C / Gas Mark 7). Place a wire cooling rack inside a baking sheet for optimal air circulation.
- Wash and Dry: Scrub the potatoes thoroughly under cold water. Crucially, dry them completely using a clean towel. Excess moisture is the enemy of crispy skin.
- Pierce the Spuds: Using a fork or metal skewer, pierce each potato 8-10 times all over. This allows steam to escape during cooking, ensuring a fluffy interior.
- Initial Seasoning: Toss the dry potatoes in 1 tablespoon (15 ml) of the olive oil and a pinch of salt and pepper. Rub thoroughly until evenly coated.
- First Bake (The Dry Out): Place the oiled potatoes directly onto the wire rack set over the baking sheet. Bake for 45 minutes. The skins should look matte, dry, and slightly shrunken.
- Second Seasoning (The Crisp Finish): Remove the potatoes from the oven. Increase the remaining 1 tablespoon of olive oil and the rest of the flaky sea salt. Use your hands or a pastry brush to rub the remaining oil and salt directly onto the hot, dry skin.
- Second Bake (The Internal Fluff): Return the potatoes to the oven. Reduce the heat slightly to 400°F (200°C / Gas Mark 6). Bake for another 30–45 minutes.
- Test for Doneness: The potato is done when you can easily squeeze the center and it gives way without resistance, or when the internal temperature reaches 205°F (96°C) or higher.
- Release the Steam: As soon as they are cooked, use a sharp knife to slice a large ‘X’ across the top of each potato.
- Fluff the Flesh: Gently push the potato ends inward, forcing the fluffy interior to burst upwards. This immediately releases trapped steam.
- Dress and Serve: Add a knob of butter (if using) and your desired toppings straight into the hot, fluffy center. Serve immediately.
