We made some delicious potato pancakes that tasted really similar to the ones we had at the Saluhall Market in Stockholm. We had them with Swedish meatballs we bought frozen from the local market 
Basically, to make them you make simple pancake batter and you grate potatoes, then… wait for it… you mix them together and cook like regular pancakes.
First, the potatoes
Grate about 3/4 pounds of potato into a bowl of very cold water. Drain the potatoes and press out as much liquid as possible with paper towels.
Then, the batter
Whisk together 1/2 cup flour, 1/4 teaspoon baking powder, 1/2 cup almond milk, and salt & pepper until smooth. Add 1 tablespoon grated onions and 1 egg and continue to whisk.
Combine
Stir the potatoes into the batter.
Cook!
Get a griddle or pan pretty hot, add some oil and then cook like you would pancakes. Flip once when the bottom is golden brown – they will take longer than just pancakes do.
Enjoy
