Ketchup

A bottle of Calber's Fine English Ketchup is in the collection of Hal Emmerich's food pantry, brought over by supply boat three weeks prior to the FOXHOUND Rebellion. It's an Italian-tomato-based food condiment. It is a fat-free way of adding flavour to many eating items, and is very low in saturated fat and cholesterol. It is also a good source of vitamins C and A. This food is very high in sodium, and a large portion of the calories in this food come from sugars. It's also known as catsup.

During the Shadow Moses Incident, Snake used ketchup as a way of escaping the Prison Cell. The red colour tricked the guard Johnny Sasaki into believing that Snake had been somehow killed, and went in to investigate it.

Obtaining it requires Snake to contact Otacon on the Codec while he is trapped the cell. To use, Snake must lie on the ground and spread the contents of the bottle beneath him. In order for it to work, Snake must remain perfectly still whilst lying down, and must get into said position whilst the guard is out of the room.

Bottles of ketchup can also be seen in Deck-D, crew's quarters on the Tanker, and in the Strut C Dining Hall of the Big Shell in Metal Gear Solid 2. Shooting at them can cause a distraction for the enemy with the mess and noise they create. The bottles in the Tanker and Plant are each from different brands, but the lettering on the covers are illegible.
