So I finished my first decorated cookie last night, 24 hours ago. I just taste tested one and the RI is nice and hard, but in the centre, where I put sprinkles, it is still soft. So should I wait until it's completely hard before I put them in an air-tight container or is it okay now? If I have to wait how long does it usually take? I'm guessing it's because the middle (centre of a flower) is covered in sprinkles so the air cannot get at it as easily?
is it still soft, or still "wet?"
When I pushed on it it was hard, but when I bit into the middle part, where the sprinkles are, under the top layer the icing was the consistency of thick buttercream.
I thin that's fine to bag and stack - in fact, that's the way my RI is always in cookies (which is why I keep saying it's not the same as the RI used on gingerbread houses) - I use Antonia74's recipe. It dries hard to the touch, you can stack and bag, but it is still soft enough in the center to not break teeth.
