Look at the beautiful golden wonderfulness…. That right there ladies and gentleman, is rendered chicken fat. Yup. What exactly is “rendered” chicken fat? Essentially, you are taking fat cut off from the lean meat of the chicken, adding water to it, simmering it for an extended period of time to break it down until it is no longer a solid, but rather a liquid, like you see above. A golden ray of culinary sunshine. Too much? I don’t think so.
