I have visitors coming in the morning and i would like to serve them fresh scones. I wont have time to make them in the morning so would it be best to make the scone dough tonight and cook it in the morning or to cook them tonight and maybe warm them in the oven when they arrive.
Weigh out everything tonight. Sieve dry ingredients, rub in butter etc, but do not wet the mix. In morning, turn on oven, add wet ingredients, egg, milk etc... roll, cut, pop in oven. Voila, fresh scones in minutes. Go on, impress your guests.
If you make the dough, the wetness will start the baking powder (either added separately or in the SR flour) start to work overnight instead of in the oven. Result is leaden scones. Mix dry ingredients and wet and roll on the morning or make the night before and reheat.
