Winged one,
The dusting powder is a substitute for talc which I have heard is contaminated with something like aluminium so never use it now. I've found silver topped sugar shakers in junk and charity shops to put it in, so it makes a very good gift.
Will have to hunt out candied peel recipes, I have made it the "proper way", and while it was miles better than the bought stuff, it was a real pain, leaving me with a very sticky kitchen. Have seen ways to do it in a microwave and a dehydrator, do you have these to hand?
best wishes
Sue

PS, If you are going to make it get saving the citrus peel, I used all sorts, oranges, lemons and grapefruit and limes. Great fun (!) and sore fingers getting the pith off with a sharp knife. I did think of freezing it to see if that makes it easier, but haven't tried that yet.
