Can you freeze food that has been prepared after the original frozen food has been thawed, prepared, cooked and cooled?
Yes, you can freeze food that has been prepared from frozen food. The United States Department of Agriculture's website has this useful guide: http://www.fsis.usda.gov/Fact_Sheets/Focus_On_Freezing/index.asp. Under the section "Refreezing," the site explains that foods can be thawed in the refrigerator or cooked and then placed back in the freezer. As the site mentions, the quality of the food may not be as good, but it is safe. A good example of this would be making lasagna from scratch, using frozen ground beef or cheese, cooking it and then freezing leftovers.
Do note, foods that have not been properly thawed are not safe to refreeze. Please refer to our webpages, http://missourifamilies.org/quick/foodsafetyqa/qafs225.htm and http://missourifamilies.org/infosheets/foodsafety/thawprnt.pdf for more information about proper thawing techniques.
