Start by ensuring all the potatoes are cut into equal-sized pieces; this is crucial for even cooking. Place the pieces into a large pot and fill it with cold water, just enough to cover them completely.
Add about 1 teaspoon of salt to the water. Stir gently and heat the pot over high heat until it comes to a rolling boil.
Once boiling, reduce the heat to medium and allow the potatoes to cook for approximately 15 minutes or until they are fork-tender. Keep an eye on them to avoid overcooking.
After cooking, drain the potatoes thoroughly. Now, it’s time to get them fluffy! Use a potato ricer, sieve, or a simple potato masher to mash the potatoes until they are light and airy.
In a large mixing bowl, combine the fluffy mashed potatoes with 1 cup of flour, 3 tablespoons of butter, salt, and black pepper. Mix thoroughly until a dough forms.
Next, on a lightly floured surface, flatten the dough into an 8-inch disk about 1 inch thick. Using a knife, cut the disk into 8 triangular shapes, much like slicing a pizza.
Now, let’s cook these delicious cakes! In a large skillet, melt the remaining 3 tablespoons of butter over medium heat.
Carefully place the cake triangles into the skillet, ensuring not to overcrowd the pan. Cook for about 4 to 5 minutes on each side or until they turn a beautiful golden brown and crispy.
Once cooked, transfer the Irish Potato Cakes to a paper towel-lined plate to absorb any excess grease. Repeat this process for any remaining cakes.
And there you have it! Serve the Irish Potato Cakes warm, perhaps with a sprinkle of fresh herbs or your favorite dipping sauce.
