Shred your potatoes with a box grater and soak in a bowl of cold water. Swish around with your hand to get out as much starch as possible, then drain.
Place a cloth over your bowl and place your potato on top. Grate over a shallot, then twist into a ball and squeeze out as much moisture as possible.
Place into a bowl and combine with your flour and a good pinch of salt and pepper. Mould into 6 equal oval shapes.
Melt your butter over medium heat with your oil then add your hash browns. Fry for 4-5mins each side OR until golden brown and crispy.
