It is possible to test a freezer's temperature using a thermometer. In a freezer without a thermometer, ice cream is a good indicator of the temperature: ice cream remains rock hard in a freezer that is adequately cold but stays soft in a freezer that is too warm.

A quicker option is to seal the food in a leak-proof bag and submerge the item in a bowl of cold water. Change the water every 30 minutes until the item is thawed, then cook it, and eat it right away. The fastest way to thaw something frozen is to use the microwave's defrost function.
