Every single person we know loves latkes, the fried potato pancakes traditionally served at Hanukkah, but why wait all year? We love latkes so much that we eat them from January through December. In this latkes recipe, we top our potatoes with tangy sour cream, green onions, and masago—tiny fish eggs from the capelin fish. You can find the roe in specialty fish markets and food stores. As a substitute, feel free to use salmon roe, which are larger and somewhat saltier. (To make this latke recipe pareve, serve it without sour cream.)For us, these latkes from our latest cookbook The Covenant Kitchen are really all about potatoes and oil. We don’t use egg or matzo meal to “bind” the main ingredient, but you will need to use russet (baking) potatoes here. They are high in starch, which serves as a natural binding agent.The latkes are cooked crisp on the outside and soft inside. We prefer to fry in extra virgin olive oil. It’s a little more expensive than other oils, but in our opinion, its fruity flavor is worth it. However, some people find that olive oil smokes faster than other oils, such as canola or vegetable oil. We have not had this experience, but you should feel free to use whatever frying oil you are accustomed to.Latkes with Sour Cream, Green Onions, and MasagoExcerpted from The Covenant Kitchen: Food and Wine for the New Jewish Table by Jeff and Jodie Morgan.

Preheat the oven to 200°F.
In a food processor fitted with the shredding blade, grate the potatoes. (You can also grate them by hand, but it is very time-consuming.) Transfer the potatoes to a large bowl. Grate the onions and add them to the bowl with the potatoes. Add the salt. Using your hands, thoroughly mix the potatoes, onions, and salt. Set aside.
In a deep-sided skillet, heat ½ inch of olive oil over medium-high heat until the oil begins to shimmer and show small bubbles.
While the oil is heating, form the potato pancakes. Using a ⅓-cup measuring cup, scoop out enough shredded potato mix to fill the cup. Hold the cup over a separate bowl and press as much liquid as possible out of the potatoes. Tap the contents of the cup into the palm of your hand and shape it into a thick pancake, pressing as much additional liquid from the pancake as possible. Set the latke on a large plate. Repeat until you have used up all the potato mix. (You may need 2 large plates to hold all the pancakes. Discard the pressed liquid from the potatoes.)
When the oil is hot enough, cook the latkes in batches. Use a spatula to lift the latkes off the plate and gently set them in the boiling olive oil. (If the oil starts to smoke or splatter, reduce the heat slightly.) Do not crowd the pancakes. Fry until the latkes are crisp on the outside and both sides are dark tan or very golden brown, about 10 minutes per side.
Transfer each batch of cooked latkes to a paper towel-lined baking dish and keep warm in the preheated oven until ready to serve.
To serve, top each latke with a dollop of sour cream. Place a small spoonful of masago on top of the sour cream. Sprinkle with the green onions. Garnish with pepper to taste.
