Preheat your oven to 190°C / 170°C fan / 370°F / gas mark 5.

Fill a large saucepan halfway with cold water.

Peel and cut the potatoes to desired size and place into the saucepan.

Once all potatoes are done place the saucepan onto the stove and bring to the boil over a medium to high heat. Add a good pinch of salt to the water.

Once boiling, turn the heat down and simmer for 10 minutes until the potato edges are getting soft.

Meanwhile, get a large roasting tray and spoon in the duck fat. Place the tray in the oven.

Once your potatoes are cooked, drain them in a colander. 

Once drained, transfer them back to the saucepan. Place the lid over the top and shake well which should allow the edges to break slightly.

Sprinkle the flour over to coat all the potatoes.

Remove the roasting tray from the oven, then add the Marmite and mix it with the duck fat.

Tip the potatoes gently onto the roasting tray. Mix to cover all surfaces of the potatoes with duck fat. Sprinkle over some sea salt, then transfer back to the oven.

Roast for 1 hour or until golden brown, turning the potatoes every 20 minutes.

Transfer to the serving plate of your choice. Enjoy!
