Potato bread is a very famous dish in Northern Ireland, but the version we were served was far from ideal. I got an original recipe from Paula McIntyre and made my own batch. Delicious! Eat it hot with butter.
The official way is to boil the potatoes in their skins, then remove the skins and press the potatoes through a press or sieve. Of course, you can also use a potato masher, but make sure it's smooth. Not too many lumps.
Add the flour, sugar and salt and mix until combined. This is easiest if you pour it on a floured surface. Knead briefly. No more than about 30 seconds.
Shape the dough into a ball and flatten it to about 6 inches in diameter. Cut it into 8 slices (wedges).
Heat a frying pan with butter and fry the potato wedges until cooked and golden brown. Serve immediately with butter!
