I absolutely love glitter on cookies. When I first started out, disco dust (and glitters like it, such as this) was still being sold as 'edible' and I happily used it (and ate it) in large quantities. Then The Authorities (in the UK) realised that it was, strictly speaking, not an edible product, as it is not digested and has no nutritional value, and therefore couldn't be sold as such.
