I ran out of flour halfway through my recipe. Can I add more after refrigeration? I started out making shortbread using a 1, 2, 3 recipe method:


one cup icing sugar
two cups butter
4 cups flour


Halfway through I realised I'm going to make just about 3 cups of flour. I continued, but the dough seems too soft and buttery. I refrigerated it.

Can I add another cup of flour tomorrow?
Sure you can, shortbread dough can be refrigerated or frozen without any issues, there's no reason you can't add the flour a day later. Coming from the fridge it will be a bit stiff but nothing you can't work with.
