Boxty

Squeeze grated potatoes as dry as possible in a tea towel. In a bowl, combine the potatoes, flour, and salt. Stir in the milk gradually, using enough to make the mixture hold to together. Let the mixture stand 1 hour. Heat a 23cm - 25cm heavy frying pan until very hot. Drop in the butter and let it melt. Pat the potato mixture into the pan with a spatula, distributing it evenly. Cook over medium heat until the underside is set and golden brown. Slide the pancake onto a plate and invert it back into the pan. Let the other side brown. Serve the pancake straight from the pan with brown sugar and melted butter.
