8 tablespoons olive oil (or tub of goose fat)
6 massive potatoes - peeled, halved
1.5 tablespoons flour
Place potatoes in pot of cold water, put on heat, bring to boil and leave for 5 minutes. Strain, let steam rise and potatoes cool and dry a little. Put oil in roasting dish and pop in oven for 7-8 minutes.
Throw flour in to potato pot, put lid on and shake pot to muss up the edges of the potatoes. Empty pan into very hot oil (or one by one with spoon to prevent splashes).
Roast at whatever temp oven is at for roast (180-200c) for about 40 minutes or until super crispy and yum.
