Place all the ingredients in a large bowl and mix with the blade of a bread and butter knife until a soft dough forms - adding a little splash of milk if necessary.
Turn dough out on to a lightly floured surface and gently pat out until it is about one inch (25mm) thick.
Cut into desired shape with either a scone cutter or a glass tumbler - do not twist while cutting.
Place close together, but not touching, on prepared baking tray. Bake for 12-14 minutes.
Remove from tray and wrap in a clean tea towel to keep warm for serving.
