In this video, Chef John reveals the key to making perfect potato pancakes, with a crispy, golden-brown exterior and a creamy, tender middle. You’ll start by grating potatoes and onions into cold water. The water is one of the keys here. The other key is, after the soaking, making sure you squeeze out all of the water; you want the potatoes to be as dry as possible. Watch the video, then check out the recipe for Chef John's Classic Potato Pancakes. Serve them simply with sour cream or applesauce. Or go all out with smoked salmon and dill. They’re also amazing with caramelized onions, sautéed mushrooms, crab salad, or scrambled eggs and bacon.
