How we tested spoilage

We stored our homemade duck fat drippings in the fridge at approximately 40°F (4°C) and held both opened and unopened samples for 60 days. During this period, we closely monitored the drippings for any signs of spoilage. We noted a slight change in color from a rich golden hue to a duller shade in one opened sample, and we detected a faint rancid smell that was absent in the unopened sample. The texture remained consistent, with no signs of mold growth. After a quick cook test, heating the drippings to 165°F (74°C) for verification, we ultimately decided to discard anything that appeared questionable to ensure safety.
