How to Render Duck Fat

The process begins by cutting a pound of duck fat and skin into small pieces, removing the oil gland if working with tails to avoid bitterness. The pieces, possibly containing small bones, are placed in a pot and covered lightly with water. The mixture is brought to a boil, then simmered with lowered heat, allowing the fat to slowly melt out of the skin and connective tissue.

As the water evaporates, the pieces start frying in their own fat. The fat changes from milky to clear, indicating it is fully rendered, and bubbling slows. The liquid fat is then strained off to separate it from the solid cracklings (cracklins). The clean fat solidifies when cooled and can be refrigerated for months or frozen indefinitely.

The cracklings left behind can be reserved for eating if bones are removed. Proper rendering ensures clear, flavorful duck fat, prized for cooking and frying due to its rich taste and high smoke point.
