1. Mix the flour and salt together, then rub in the butter; add the sugar, and the beaten egg and milk to make a thick batter. Add essence or extract if using.
2. Cook 2 or 3 at a time by dropping spoonfuls of the mixture on a moderately hot, well-greased griddle, or a heavy-based frying pan.
3. Cook until the underside is golden brown and the top is covered with bubbles, about 3 minutes.
4. Turn and brown on the other side. Serve buttered, hot or cold with honey, jam or maple syrup.
The baking griddle should be well-greased, then heated until a little water sprinkled on the surface skips about in balls, evaporating. A heavy cast-iron frying pan makes a good substitute. These freeze well once cooked and cooled.
