Bacon fat goes through a coffee filter into a 32 oz freezer container and then gets saved in the fridge to use for extra flavor when I cook something that needs it.
These containers work wonders for smaller food storage. They are reusable, can deal with heat straight from the stove without melting and they will last for years in home cooking... I have the 8, 16 and 32 oz versions
