Peel your potatoes and shred them with a cheese grater or food processor.
2 lbs russet potatoes
Cut the onion around the core. Remove the outer paper-thin layers and discard the core and peels. Shred the onion with a cheese grater or food processor, too.
1 large yellow onion
Mix the shredded potatoes and onions together. Then, use a cheesecloth to drain excess liquid over the sink. Add the egg, flour, and a crack of salt and pepper and use clean hands to mix well.
1 large egg, 1 ½ tablespoons all-purpose flour, salt and pepper to taste
Get the oil hot over medium heat. You should have about 1 inch of oil in your pan. After a couple of minutes, make sure your oil is hot by tossing a piece of potato in. If it starts sizzling right away, your oil is ready!
½ - 1 ½ cups mild olive or vegetable oil
Shape the latkes with your hands by grabbing a handful and forming into round balls. At this point, you can assess the consistency. If the latkes seem too wet, add a little extra flour.
Carefully drop the latkes into the hot oil and use a spatula to press down to flatten them. When you see the edges starting to brown, flip and cook until crispy and golden brown on both sides (about 5 minutes each side). As you continue to cook more latkes, add more oil as needed.
When the latkes are ready, transfer them onto a paper towel to soak up the excess oil. Add salt and pepper to taste, garnish with parsley (optional) and serve with sour cream or garnish with cinnamon and serve with apple sauce.
