We keep being told that animal fat is dangerously unhealthy and that plant oils are healthy. We have found that the fat we separated out from our Thanksgiving turkey dinner did not solidify in the refrigerator. We did get some mushy granules, but it poured easily. It certainly did not solidify any granules at all at room temperature (about 65º).
We did have to heat it until all the bits were crunchy to get rid of the smell, so it is golden brown. Next step is to see how well it will burn in an oil lamp, of which we have many.
