Preheat oven to 200C.
Boil potatoes for 10 minutes, or until just soft.
Add the fat to a hot, heavy-based saucepan and place over high heat, then add the drained potatoes, flat side down. DON'T BURN YOURSELF, OR SET FIRE TO YOUR HOUSE.
Get a crispy golden colour on all sides. Once all are crispy, transfer the potatoes to a baking tray.
Drizzle with a little of the warmed fat, then sprinkle with the paprika, thyme leaves, garlic, sea salt and black pepper.
Roast for 20 minutes, tossing occasionally until they are super crispy and dried out a little. The centre will be like mashed potato and pretty much the best vehicle ever for all kinds of sauces, gravies, meat juices, whatever - all of it.
