Heinz’s advertising concept for its Tomato Ketchup brand is simple and clever. It takes the message you might expect - ‘sauce makes your meal nicer’ - one step further, to ‘sauce makes your meal.’

So, thanks to a bit of clever camera trickery, blocking and CGI, we witness a mum squirting some sauce on what appears to be an empty hot dog bun. Its very application results in… the magical appearance of a succulent sausage!

The trick is smartly repeated - by a host of good-looking people, over a breezy soundtrack - with burgers, Bacon, fish fingers and chips. It isn’t the healthiest line-up (though the final shot, of a bottle sliced like a fresh tomato, attempts to make up for that), but it is a delicious-looking one.
