Ok pro tip for getting rid of your grease that doesn’t assume you have infinite containers lying around or make you wait forever for it to solidify.
Put a sheet of aluminum foil down over your drain so it creates a cup. Then pour your grease in that cup. Then drop an ice cube in if you feel like it.
Then just lift the edges and twist the top of your foil and put it in the trash.
Just let a few sheets of old newspaper soak it up and burn it in the stove or the barbecue, done. Have none of those, just throw the hardened paper in the trash.
This all probably sounds nuts, but here are my oil systems:
I wash out and recycle glass jars, but peanut butter jars are difficult to clean and will end up getting fat into the water system. So I keep the peanut butter jars for oil.
I also keep a bendy, steel decorating pallet in the kitchen for scraping out fat from the grill tray and rack. You’re left with some fat that you can wipe off with kitchen paper, which you can also use to wipe the pallet knife. Then washing up liquid and a splash of boiling water from the kettle.
There can be quite a lot of oil in leftover food, like sauces, too. I use a silicone spatula to scoop it off before washing.
I let it cool and then scrape it into our food waste bin. (I don’t know if grease composts but for us it’s moot; the city doesn’t compost food waste but instead makes it into pig feed or something.)
My sister once asked if I could help with the kitchen sink in her house as it was blocked. I started taking waste pipes off and quickly realised there's a bunch of sardines stuck in one pipe. Her 15 year old daughter had shoved fish down the waste pipe of the sink rather than putting them in the bin. I still can't understand the logic in her head. Surely it's more difficult to push fish through the small holes at the bottom of the sink than it is to take 2 steps towards the bin.
You can actually pour it into a can or container, put a wick (or make one out of paper towel) and burn it like a candle. The aroma actually isn't that strong since it's mostly fat and it doesn't sputter or anything. The solids sink to the bottom while solidifying.
Cook bacon in the oven in aluminum foil (it's better that way anyway) put paper towels in to soak the grease crumple it all into a wad and throw it away in the trash... ?
In Japan there's a powder you can buy at shops that solidifies any pools of grease you drop it into, so you can then scrape it into the garbage.
I was going to share a link but all I could find was Amazon product pages and greasy blogs funneling you towards Amazon product pages, but you can find it by searching "Japan grease powder".
