All this talk of jam gave me a scone hankering ! lol I always make mine the same way, simple, quick and cheap. The trick with scones is a light hand and a fast oven.
1lb self raising flour
buttermilk, sour milk or milk to mix
Cut butter into flour with a knife, then rub in lightly.
Place on baking tray and bake in a really hot oven for about ten minutes until risen and golden, cool on wire rack
