Work doesn't have to be a chore. Launching a series looking at dream children's jobs, Lucy Rodgers from BBC News Magazine speaks to a professional chocolate taster.

As far as fantasy jobs go, chocolate tasting must come pretty near the top of many people's lists - children and adults alike.

However, sampling and buying the best sweets the world has to offer for luxury Piccadilly department store Fortnum and Mason is probably beyond most chocoholics' wildest dreams.

That is what Darren Williams does for a living.

Any tips? Darren has learned to spit (and resist a lot of chocolate!) and also says,

"You do have to eat things you don't like, but you have to get over that. It doesn't stop me doing that part of the job."
