Get your flour and measure out 2 tsp.
Sprinkle the potatoes with the flour.
Give them another shake or two so they are evenly and thinly coated.
Carefully put the potatoes into the hot fat.
They should sizzle as they go in.
Then, turn and roll them around so they are coated all over.
Spread them in a single layer, making sure they have plenty of room.
Roast the potatoes for 15 mins, then take them out of the oven and turn them over.
