am making these and it's a disaster, not a creamy mixture when i put butter, SR flour & icing sugar into the bowl, it's more like a crumble mixture, food mixer blew up so i'm doing it by hand, nothing's happening, didn't read the recipe properly so didn't realise you have to chill it for an hour after it's a dough either, so the friends who are arriving at 2.30 won't arrive to the smell of baking cookies...what can i do?
