Sift the flour and baking powder together.
Add the butter and rub into the flour to make fine breadcrumbs or put them into a food processor and whizz to make fine crumbs.
At this point depending whether sweet or savoury add the sugar and fruit or cheese and pepper into the mix.
In a separate bowl, add 100ml buttermilk to the quark and stir well to mix.
Make a well in the centre of the dry ingredients, add the quark and mix to a soft dough adding the remaining quark if needed.
Tip the dough out onto a lightly floured surface and until gently press the dough flat to about 4cm thick.

Transfer the scones to a baking tray and brush the top of the scones with egg.
Bake them for 15-20 mins until risen and golden brown on top.
