In the US chilli con carne is most commonly referred to simply as 'chili', whereas in the UK the full name 'chilli con carne' is typically used. There may be some variation in common ingredients and what it is typically served with although the essence of the dish is still the same.
This recipe is based on the type of chilli you will most commonly find in the UK, where chilli is also spelt with two l's and if you asked for a chilli you would get a chilli pepper rather than a steaming and spiced beef stew!
