Boxty

Source - Also What is it? 

The recipe below will yield 10 pancakes - I think that will be enough for the 8 of us, but feel free to increase the recipe if you think people would like more!

 Ingredients

• 2 pounds potatoes
• Kosher salt
• Freshly ground black pepper
• 1/3 cup all-purpose flour
• 1/4 cup whole milk
• 1 large egg
• 3 tablespoons unsalted butter
• Sour cream for serving 

Method

Peel half the potatoes. Cut the peeled potatoes into 1-inch pieces. In a medium saucepan, cover half the potatoes with salted water and bring to a simmer. Cook until the potatoes are tender, about 15 minutes. Drain the cooked potatoes and force through a ricer into a bowl.

Peel the remaining potatoes and grate with a box grater. Wrap the grated potatoes in a kitchen towel and squeeze as much liquid from them as you can. Transfer the grated potatoes to the bowl. Stir in the flour, milk, egg, 3/4 teaspoon salt and 1/2 teaspoon pepper.

Form the batter into 1/3-cup-sized patties.

In a large heavy skillet, heat half the butter over medium heat until hot, then cook the patties in batches, turning occasionally, until golden, about 8 minutes per batch. Cook the remaining patties in the remaining butter. Serve with sour cream.

Make Ahead - store in refrigerator and re-heat before serving in 325 degree oven until hot
