How to Strain, Separate, and Store Duck Fat

  1. Strain the melted duck fat through a fine-mesh strainer to remove all solids. 
  2. Separate the liquid fat from the duck juices (which won’t keep nearly as long as the fat). If you own a fat separator, now is the time to use it, but you can also simply spoon the fat off the top of the juices.
  3. Store the separated fat in an airtight container for months in the fridge or even longer in the freezer.
