Those who have bought a breakfast sandwich from a greasy spoon cafe will have no doubt been asked whether they want lashings of red or brown sauce to go with it. And if you usually opt for the brown option, you'll most likely be familiar with the HP brand.
The range of sauce itself is most popular across Great Britain, and was initially launched back in 1895 - but have you ever wondered what 'HP' stands for?
Upon a first glance, it may appear that HP is the initials of the person who created the brand - but that would be Frederick Gibson Garton, which doesn't match up. The Mirror also reports that one could assume that it's got something to do with Heinz - who have owned the product since 2005 - but that's also incorrect.
