How should I store spare royal icing?
After making a gingerbread house yesterday, we have some leftover royal icing (I only made 1 egg's worth, but it was still too much). How should this be stored for a few days?
While dried royal icing is clearly suitable for room-temperature storage, I'm not sure if the same hold when it's still wet (in a sturdy plastic piping bag).
In case it makes a difference, the egg I used was unwashed and unrefrigerated, as is normal here (though this one came from a household flock of hens not a shop). Also it was a stiff construction royal icing - egg white and sugar just stirred vigorously together, with a little water added as it was too stiff at first.

I was hoping for something definitive, but for completeness, this is what worked for me: I kept it in the plastic piping bag at room temperature.
It dried at the open end where I'd been piping, but after breaking off the dried bit it was still usable a few days later and tasted as it should. It's essentially pure sugar, so the water activity should be too low for it to spoil - it's not surprising that it kept well.
