Hasselback roast potatoes

Set the oven to Gas Mark 5 or 190°C. Make a series of deep cuts along the top of the potatoes, without cutting all the way through. Place on a shallow baking tray.

Melt the goose fat and brush over the potatoes. Sprinkle salt and pepper over. Roast potatoes in top of oven (above the turkey) for 1-1¼ hours, brushing them occasionally with any extra goose fat, and using a small knife to help open up the slits. The potatoes should be light golden and feel tender when pierced with a fine knife.

Remove from the oven and serve them immediately.
