Can you keep uncooked bisciuts in fridge chilling for a few hours before baking?

The recipe is slightly different from mine, but shouldn't be any problem; I often leave the dough out wrapped for a couple of hours before forming, and leave the biscuits out after forming for an hour or so; you could probably just cover them and leave them on the counter. If you chill them it will make a very slight increase in the baking time.

Chilling biscuits is normally fine. They'll probably need about 3-5 extra minutes in the oven though.
