A few weeks ago in the Saturday times mag there was a pastry recipe which iirc included quite a bit of gruyere cheese but a lot less butter than usual. I can't find it now and googling for cheese pastry recipes the ones I've found seem to have pretty much the normal 2:1 flour :fat ratio plus cheese which seems to me would be very greasy. Does anyone have a recipe in which the cheese substitutes for some of the fat please?
