Of course it is good for cooking more than once, but many who do it
for Thanksgiving only cook that way once a year. You can look up a
local biodiesel producer on the internet, don't make a special trip and
use more energy than you save, wait until you have an errand to run to
that part of town anyway. (You can store and carry it in the same
container you bought it in.) Or you can pour it into the grease bin
behind a local grill, just don't throw it away. It is usually peanut
oil, which is great feedstock for biodiesel.-Jitney
