Ketchup Packet Explode

Ketchup packet explosions are a surprisingly common problem for many people. Whether it be from a faulty packet, or from simply squeezing too hard, these explosions can be a real mess.

If you do end up with a ketchup packet explosion, try to contain the mess as quickly as possible with paper towels or a rag. Be sure to clean up the area thoroughly to avoid any further messes.

Bad Heinz Ketchup

Bad Heinz Ketchup is an absolute disappointment. It has an artificial flavor that leaves much to be desired and an overly sugary taste that leaves an unpleasant aftertaste. The texture is too thick, making it hard to spread and often clumping when used. Furthermore, it does not have a strong tomato flavor, making it difficult to enjoy. The color is usually a deep red and not the vibrant red of a fresh tomato. All of these factors make it difficult to enjoy and not worth the price.

Expired Ketchup

If you eat expired Ketchup, it’s fine to eat it again. Despite the fact that ketchup has a date on it, it will not expire within a month or two. Quality is the sole reason for putting this date on your ketchup, and it is often sufficient for months after that. It is safe to eat it if it does not appear to be deteriorating.
