Today I watched an episode of Food Unwrapped that dealt with glace cherry's and their production.
I have worked in lab dealing in food technology for many years, there was a lot of vital information omitted ....or not included in that particular episode, I know the process that (in this case cherry's) go through as well as the ingredients and chemical used to achieve the end result, very toxic, one little example... the person interviewed stated the colours used to colour the fruit was "natural" completely false, or that persons definition of natural does not meet the standards or requirements of most first world countries. I would strongly suggest that using this type of processed fruit be kept to a total minimum or IMO ...NOT AT ALL there are plenty of other options for baking and decorating fruit cakes....If you only know the complete truth about the process, you would understand my perspective.
Do your own research & choose wisely.
Kind regards r.
