Yummly uses data from multiple databases to determine the average shelf-life of each unique ingredient in your Virtual Pantry. We may also use information about recipes you've told us you made recently and how frequently you add an item to your Shopping List to estimate when you have likely used everything up. Once we've determined that an ingredient is either Running Low or Expiring, we'll move them to that category and prompt you to take a look and confirm.
Something look not-quite-right? You can edit the expiration date or category of any ingredient in your pantry by swiping left on the ingredient and selecting "Edit" from the menu. Note that items in the Running Low or Expiring Items categories aren't included in your Pantry-Ready recipe search results.
