I usually use duck fat for fries. Also great. I’ve never cooked with tallow before. I’d like to try it one day.

I bought a jar of duck fat, how long does that keep? Tallow is basically immortal. I should try to do some potatoes in duck fat tonight.
They last quite a while. I've kept duck fat in an airtight container and it lasted for several months. It's generally cool where I live so they last a bit longer. I think they'll keep for a long long while when refrigerated or frozen.
