Preheat oven to 200C. Grease a baking sheet.

Sift the flour, salt and baking powder into a bowl. Rub in the butter until the mixture resembles fine breadcrumbs.

Using a knife to stir it in, add enough milk to give a fairly soft dough.

Gently roll or pat out the dough on a lightly floured work surface to a 2 cm thickness and then, using a 6 cm plain cutter, cut out rounds.

Put on the baking sheet and brush the tops with beaten egg or milk. Bake for about 10 min until golden brown and well risen.
