I don't save my pig bacon fat, it goes in a jar that when full gets dumped directly in the trash. Make sure one of your kids doesn't spill said jar though, cause there is no smell when it just sits there, but if it's disturbed at all, man does it stink.
If you don't keep it in the fridge till you're ready to toss it, the fat goes rancid, hence the stankonia. Not a problem if you keep the lid on the jar though.
