I saw these 'homemade' iced gems in a magazine and have wanted to make them ever since!
It's a biscuit base - rolled out and cut into circles (you're supposed to use a fluted circular cutter, but I only had a petal shaped one).
You push a thumb dent into each one (because they rise in the oven).
This is what the mini biscuits look like once cooked
The top is royal icing (made according to the packet instructions), coloured and then piped. It takes a few hours to set.
