Grate the potatoes and put them in a bowl, then sprinkle with salt and pepper (about 1/2 - 1 teaspoon of salt, depending on amount of potatoes).
Massage salt and pepper into grated potatoes - to draw out the water and leave for 5- 10 mins. Line a colander with a clean tea towel and tip potatoes into it, to get rid of most of the liquid, then
gather up the tea towel and squeeze like hell to get rid of all moisture!
Heat a generous amount of butter and olive oil in a shallow pan, then form the potatoes into a 2-3 cm patties and place them into pan. Cook over a moderate heat for about 15 minutes (without browning too much) until potato patty is set. However, during the process don't be tempted to move them/mess around with them. Just let them sit in the pan until set.
Then flip over and cook on the other side in the exact same way. Then Increase heat to brown both sides, until you achieve the desired colour and crunch - and serve!
The bit in bold, she says is *crucial* (and I did this for her as I'm much stronger) - you have to thoroughly extract every last bit of moisture out of the potatoes, before cooking them, as that's how you get them to be so light and crunchy when they're cooked:)
