I’ve begun eating bacon again, and had forgotten how good potatoes cooked in bacon grease taste.
In a old jelly jar on the stove.
We throw it out once in awhile and start over with a clean jar. Pickle jars work too. 
We don’t use plastic containers for grease.
I use a plastic tupperware-type container (a different brand, though) and keep it in the fridge.
Cheap plastic container and keep it in the freezer. Stays usable pretty much forever that way.
Do you pour the hot, liquid grease directly into the container?
In a covered jam jar in the fridge. I save the old lids, as well as the jars.
I always wash out the old jam jars and such, and re-use them. It drives my husband nuts to see all the old jars. Until HE needs a jar that’s usable, but disposable.
And yes, I pour the warm, liquid grease directly into the jar, but very slowly, because the jar is cold glass and might crack if it gets too hot too suddenly. I generally let the grease cool a bit, so it’s not burning hot.
I know that my grandparents and great grandparents used to keep a can of bacon grease on the stove, but I prefer to refrigerate mine.
For grease that I’m not planning on saving and re-using, I pour into an empty soup or bean can, and then throw it away when it’s full. Stuff like hamburger grease, mostly. If I fed birds, I’d save the grease and mix it with birdseed, but around here, the only birds that will come around to be fed are grackles, which are ugly and noisy and mean.
In mah belly!
In a tin can in the fridge. I keep it covered with a piece of plastic wrap and a rubber band. I pour hot grease right on top. I use bacon grease almost every day. When my supply starts to get low I cook more bacon.
This. Only I say “Tummy”.
Yep, straight from the pan. I pour off most of the bacon fat before I fry the eggs in what’s left behind, so that fat is still at bacon-frying temperature. I just checked and the container is a Rubbermaid Easy Find Lid container, but probably any decent plastic container would work.
In my house pig. Her name is Squealy Logan, Esq.
But … but … cannibalism?
Pigs will eat pork and ham if given the chance. They’re quite fond of it, or so I’ve read.
My Mom used to use old coffee cans she’d washed out and kept it in the freezer.
An old pickle jar in the fridge. I don’t pour boiling hot grease into it, but don’t wait until it congeals either.
When it’s full, it gets tossed into the trash.
I use this. It has a screen on top to catch the bacon solids, which can then be scraped off. I use bacon grease for frying and baking lots of things, but it’s especially good for chicken breasts and roasted brussels sprouts.
Old coffee can (the kind with a plastic snap on lid) under the sink. When full, it’s thrown out. Just like Mom does it.
Pony up with the recipe!
Awww… poor Mom.
We save most jelly and pickle jars just for this. There small enough that we never have to deal with large volumes of it which, if leaked, could get messy.
Old juice containers work well for this. You know, the cans that frozen condensed juice come in? Those.
