Bakers! Quick I have an urgent question!

[MyArseIsbiggerThanYours]

I am making heart shortbread biscuits (biscuits cut out already and ready to go in oven). I want to make a smaller heart on top in coloured sugar.
How do I get the sugar to stick on and do I do it before baking or after?

I've read about brushing the biscuit before baking with egg white, sprinkling sugar and cooking but that wasn't for shortbread. Any ideas?

Thanks.

Edible glue is your best bet or may try a very thin layer of watered down icing sugar hope that helps

Thanks. Before or after cooking do you think?!

If you are cutting the hearts to go on top out of thick ready roll icing, you can dampen the bottom or use a very thin layer of icing sugar icing to stick it on. Do this after baking, after they have cooled.

The hearts will be made from pink granulated sugar (picture glitter on a Christmas card!)

Like these but I wanted the hearts on top to be a neat shape

sorry got distracted,after baking once they have cooled

Ok, so out of interest in case anyone else does the same thing. I didn't get your reply in time (outrageous, RL interrupting serious mumsnetting )

I lightly brushed egg white on before baking and sprinkled the sugar on before they went in the oven in the end. Must say they looked fab and tasted good too so will stick with that method I think!
