HP Sauce is a statement in many homes - but not many people actually know what the letters stand for.
The brown condiment is a key part to many people's kitchen cupboards. It is often used to make a full English breakfast even more tasty, and no plate of sausage, bacon and hash browns would be complete without it.
While most people are more concerned about what is in the bottle rather than what is on it, others have often wondered where the brand's name comes from. Kept simple, it is just made up of two letters - "HP".
