In pursuit of the perfect kilogram
EU lab tests chocolate, toast and now, molecules


Searching for that perfect piece of chocolate? Belgium is renowned for the best. But rather than one of the country's many sweet shops, head to an obscure town in the north of the country.

There, on a leafy campus set among farms and canals you will find what is quite literally the standard in chocolate: pure cocoa butter at 100 euros ($121) for 10 grams (0.3 ounce).

Here, at the European Union's Institute for Reference Materials and Measurements chocolate is just one of the things for which scientists have created accurate samples.
