Buy a good quality milk chocolate - organic is a better choice.
Store at a temperature between 15 - 20C. Wrap in foil. On hot days store in the fridge to avoid a greyish bloom appearing.
Tips & Tricks:
Chocolate that has a grey bloom is not off and will not affect you adversely. It is caused when cocoa butter melts to the surface of the bar. The texture of the bar will be effected becoming dry and less creamy.
One serve is only 20 grams - a few squares at most, so savour it!!
If heating chocolate, avoid high heat - melt grated chocolate in a covered, dry glass bowl suspended over a pan of gently boiling water. Leave for five minutes before stirring, until all the pieces have completely melted.
