I use this almost anywhere butter is called for; on toast, for pan-frying, and my specialty, grilled cheese. If you get nothing out of this thread, I want you to make grilled cheese using bacon grease, it will change your life!
Well, apparently if you combine a full jar of bacon drippings, a cupboard full of chemicals, and one bored Phineas who has been reading "Fight Club," then Bacon-Fat soap is the result! :lol:
I combined the fat with twice its volume of water and brought the mixture just to a boil:
After stirring the fat/water mixture to make sure all the clumps of fat were melted I placed the mixture in the fridge. It sat there in the fridge for ~2 hours before I got extra bored and moved it to the freezer to cool quicker. After 1 hour in the freezer it looked like this:
This process is called "rendering" and separates the fat from the charred bits of pig-flesh and other impurities present in bacon drippings. After 2 hours in the fridge and one in the freezer, most of the fat had floated to the top and solidified. The fat is separated from the water; this step can be repeated as many times as necessary to get really clean fat. I didn't bother to render again, I'm just messing around tonight:
To make soap I need to add lye and water to the rendered fat in a ratio of 1lb fat : 6 oz H2O : 2 oz lye.
This ended up being 363.7g (.8011lb) of fat, so I used ~4.8 oz H2O and 1.6 oz crystalline NaOH.I made this solution as the rendered fat heated, just enough to liquify. I transferred the fat to a plastic bowl and added the ~4.8oz of lye solution.
The mixture was whipped with a wooden spoon for 15 minutes, until "traces" began to form. The mixture was the consistency of pancake batter at this point:
I cut the top off an orange juice container to use as a mold:
And poured the fat/lye mixture in:
In the time it has taken to process the pictures and write the post, the liquid has hardened so that the "mold" can be turned completely upside-down! After 24 hours I will de-mold the soap and slice it into bars. These bars will be covered with plastic wrap and allowed to cure for 2-3 weeks.
:lol: At least I know I will be clean when the zombie apocalypse finally comes...
