Map your Recipe can optionally show you the top 3 producers of a select number of crops. It will link to a website that maps the top 20 producing countries.
Map your Recipe can optionally also give you the year the word for a food stuff (i.e. 'apple', 'potato') was first recorded in English. Though not always precise, etymology adds a fascinating secondary window on the history of our food.
