Here's how long you can keep condiments after you open them

Wonderlane/FlickrMost condiments stay fresh longer if they’re kept in the refrigerator.
  • Condiments like hot sauce and Sriracha can remain good for a year or more after you open them.
  • Certain condiments, like salad dressing and mayonnaise, need to be refrigerated after they’re opened to maximise their shelf life.
  • Some condiments, like yellow mustard and ketchup, can be stored in the pantry or refrigerator after they’re opened, but their shelf life varies depending on the storage method.

There are dozens of condiments out there, and chances are you have some of them in your kitchen. But because they’re typically used in small quantities, they tend to linger for a while.

Although condiments are designed for the long haul – many remain good for weeks or months after opening – they all eventually expire. Here’s how long you can keep certain condiments after you open them.

Ketchup stays good for up to six months after opening.
