We've got two "crocks"...well jars.
One gets tha bacon grease, fat from the roast pork belly, or lamb, lamb chops and fat from the smoker. Stays in the fridge, and is used to grease the pans if we are pan frying stuff, or do baked vegetables with a roast.
The other is the "miscellaneous fats...they get used to light fires/charcoal, but usually thrown out.
We have wagyu dripping, duck/gose fat, and sometimes lard in the fridge.
