Method
Rub the flour, sugar and butter together with your fingertips until the mixture resembles breadcrumbs.
Add enough egg to bring the mixture together to form a stiff dough.
Flour your hands and shape the dough into a sausage, about 5cm in diameter. Cut into 2cm slices and place on a large baking sheet, well spaced, as they will spread when baking.
Make a small dent in the middle of each with the end of a wooden spoon, them drop in a teaspoon of jam.
Bake for 10⁄15 minutes until slightly risen and just golden. Cool on a wire rack.
