Creating authentic Irish Potato Farls is straightforward if you follow these steps:

1. Cook the Potatoes: Boil the potatoes in salted water until tender (about 15-20 minutes). Drain and let them cool slightly.

2. Mash the Potatoes: Once cool enough to handle, peel and mash the potatoes in a large bowl until smooth.

3. Mix Dry Ingredients: In another bowl, combine the all-purpose flour, baking powder, and a pinch of salt.

4. Combine Mixtures: Gradually add the dry ingredients to the mashed potatoes. Mix until a dough forms. You may need to adjust flour amount for consistency.

5. Shape the Dough: Turn the dough out onto a lightly floured surface and form it into a round disc, about ¾ inch thick.

6. Cut the Farls: Cut the disc into quarters, creating four wedges. You can also cut them into smaller triangles if you prefer.

7. Fry the Farls: Heat the butter in a large skillet over medium heat. Fry each wedge for about 5-7 minutes on each side until golden brown and crisp.
