It is unacceptable to throw away any type of cooking fat– whether liquid or solid – in the sewers. This can not only lead to personal plumbing issues, but blockages throughout the neighborhood. and — to the extreme case-basements full of sewers.
Lots of cooking oil, even cheap vegetable products, can be filtered, cleaned and saved for later use, but I don’t always feel like doing all of this, especially if I’m working with a grocery brand canola oil.
To get rid of the oil you don’t want to clean, just pour it into a container, then throw that container in the trash (or take it to a oil recycling program), but rarely do I have extra disposable containers, such as milk cartons or coffee cans, lying around.
Do you know what makes the best used oil canister? The bottle in which said oil previously resided. Unlike a carton of milk, a carton of inexpensive vegetable oil is durable and sealable, and (unlike a coffee canister) it’s also not worth cleaning and reinstallinguse elsewhere at home (it’s just too greasy).
I keep my bottle of trash oil under the sink, right next to my trash can. Tthrough years of pouring chemicals in various laboratories, I don’t personally having trouble shedding fat directly from a saucepan to the bottle, but you can keep a cheap plastic funnel there if you need to protect yourself from the mess spills. Once my cooking fat has cooled to the point where it won’t cause injury if I spill it on my skin, I pour it into the bottle, close it and put it back in place until I need to remove it. . oil again.
I have found that the timing of using an empty vegetable oil bottle works exceptionally well. I strain and save my bacon fat and lard, so it’s usually just the inexpensive liquid oils that end up in the bottle; I tend to fill my trash bottle just when I’m running out of fresh oil, so there’s rarely a time when I’m without a vacuum to use in my disposal system. It’s a elegant system–or as elegant as removing oil becomes.
