Over the last few days, as time has become meaningless between Christmas and New Year's, many of us will have consumed more chocolate than we may have thought humanly possible. No judgement here, 'tis the season after all.
However, it turns out there's a lot about chocolate that many people don't know - including the science that goes into making it and just how tricky it can be to come up with new flavour ideas that will actually work.
We recently visited the test kitchen at the Nestlé factory in York to learn all about how chocolate is made, how they brainstorm new products and general secrets about the sweet stuff.
