Potato Cakes

This is from my sister. She shreds her potatoes, but you can also buy them shredded in the grocery store. yuuuuuuuuuuuuuuum

baking potatoes, cut in half
2 tbsp butter
2 tbsp olive oil
salt and pepper
chopped green onions, to garnish, if you want.

Boil the potato halves for about 15 minutes. They shouldn't be cooked all the way. Drain them and put them in the fridge for about 30 minutes so that they're easy to handle. Then coarsely shred them! Melt the butter and 1 tbsp oil in a non-stick skillet and put the shredded potatoes in there, pushing down with a spatula or something.Let them cook for 10 minutes, then put a plate on top of the skillet and flip the potato cake onto the plate. Put the remaining 1 tbsp oil in the skillet and slide the potato thing back into the skillet so it can cook on the other side (cooked side up). Let cook 10 more minutes, slide onto a plate, season, and sprinkle with the green onions!It is so good, like a giant hashbrown. And crispy.
