Why do we cook? To create flavour, to aid digestion and to release nutrients from our food.

Every time we fry, steam, boil, or bake a series of chemical reactions take place that are key to a dish’s success.

In this programme Ruth Alexander puts questions from the BBC World Service audience to Dr Stuart Farrimond in the UK, author of ‘The Science of Cooking’. Susannah and Aaron Rickard in Australia tell Ruth about the chemical reactions they discovered when researching their cookbook ‘Cooking with Alcohol’. And Krish Ashok in India, author of ‘Masala Lab: The Science of Indian Cooking’, explains the science behind the culinary wisdom of your parents and grandparents.
