Instructables
Soap can be made from just about any kind of fat. Even though fat from bacon, called lard, isn't the finest of fats to use for making soap, it somehow seemed to be the most exciting. Why? Because bacon is amazing. It has an almost mystical power to it and is a food that can be craved to almost no end. I figured what better way use the extra grease I had from cooking bacon then to turn it into soap!

Step 1: Find Bacon Fat

You can get bacon fat from a variety of sources. I got my bacon fat from working as a white water rafting guide over the summer. Day three of a five day rafting trip means bacon for breakfast, lots of it. I collected the rendered fat in plastic water bottles with the original intention of using the grease to make a bacon fat bomb - basically a concentrated grease fire, but what didn't get used to make grease bombs followed me home and sat on the shelf for a while. After cooking bacon a few times in my house, I had a little more than a quart of rendered bacon fat ready to go.

You can render your own bacon fat by just cooking bacon - I would cook up at least 10 pounds of bacon if you want to render enough fat to make a sizable batch of soap (my one liter of fat came from around 10 pounds of bacon and yielded about a dozen bacon soap strips and about another dozen small to medium sized bars. You can cook less bacon if you want to make less soap.

The fattier the bacon you buy for this the better results you will have. Also, cooking it on the stove in a pan is going to be the way to go here - don't try any microwave tricks, you won't render nearly as much fat. Don't worry if lots of black and brown bacon bits get into your rendered fat, they can be purified out later.

You can also buy lard directly at the grocery store - although something about just buying the lard without the bacon seemed to be like cheating when doing something as epic as turning bacon into soap, but if you want to save some time and money - buying the lard direct would be the way to go.

***Note: I have found that a good way to clean dirty bacon fry pans is to pour old coffee grounds into the pan (this was taught to me on the river), let it sit for a bout half an hour and then do some scrubbing. The blackened crud on the bottom of the pan comes off much easier this way than if you try to attack it head on.***

If you're going to be saving your bacon fat over any length of time, get yourself a nice big plastic or glass jar. Remember to let the fat cool a little before pouring it into your container so you don't crack or melt it.

Didn't see anyone asking this crucial question so I'll ask... You mention not getting metal anywhere near it because of Lye reacting to it but your hand mixer has a metal blade on it. I have one just like it. Is there a point in the mixing process where introducing metal to the mix is ok?

Good Job, But , I use my bacon fat in seasoning green beans or making country gravy. I would just use old fashion lard instead.

All your links are still dead.
nice
You can also put your tongue very near the soap, or on the soap. If it tingles like a 9 volt battery, it needs to cure longer.

Bacon soap is wonderful and I use mine in many ways,washing floors,washing walls,washing hands ,making laundry detergent. I collect bacon fat from our town community brunches.

I have to say, this made me really really sad... All that wasted bacon...

may have to try this sometime though! I just don't know when I'll have enough bacon to waste to do it. Would it also work to buy a tub of lard and use that?
@ thecheatscalc -- You don't have to waste bacon when you do it... just save up the grease from a few breakfasts. My grandma had a grease can that she poured grease into. When it is full then you can turn it into soap. I am totally going to try this recipe!
Wasted bacon. Unless somebody washes your mouth out with it?
meh i guess if your gonna wase bacon like that this IS one of the better ways
It's not wasted!
It's a perfectly good excuse to cook and eat enormous amounts of bacon!

this is weird. In my country only poor people do this... with extra fat from pigs... and some detergent... but is low quality soap... and too strong for skin... but nice that u like to work
Not sure if it is a different recipe where you're from. This soap is not necessarily too strong for the skin, we use it in the bath all the time. It is also great for relieving itching due to poison ivy!

Thank you so much for posting this! The question for me is if the soap had a strong bacon smell to it? I would like to use bacon fat for soap, for utilitarian/allergy purposes but wonder if it has an overt smell that might be masked by a fragrance. I.e. I want to make regular allergen-free soap (except for the fragrance).
My grandparents always used old bacon grease to make their lye soap, and it did not have any real bacon scent after saponification. The scent of this particular soap is most likely all due to the bacon bits. You can also add fragrance oils to plan lye soap to give it a more "soapy" scent. The plain soap is pretty neutral.
I see this is an older thread, so im not sure if your still doing this or not...

BUT To marble your soap use a toothpick. I think a longer, plastic implement might be better, like a plastic fork with 2 tines removed. Lay down a thin layer of red, then a thin layer of white and have a friend drag the fork though the soap longways. Dont lift the fork out till you get to the end, then left straight out and start again at the beginning. doing this 2-3 times should give you a good effect.

WHY WAS THERE BACON IN THE SOAP!!!!!

I MADE MAH SELF!

This was probably said 1,000 times but...

WHY WAS THERE BACON IN THE SOAP!!!
So you'll taste better? Was that a trick question?
I MADE IT MAHSELF!!!!!
It was quite clearly stated. The "Bacon bits" (Actually artificial and, in fact, vegan) were in the soap to provide flavour and to act as an exfoliating agent.

this project is hilarious.
to create more realistically-marbled soap, it might work if you think of painting the white streaks onto both sides of the strip of soap, as opposed to having bacon that's actually marbled in cross-section. kind of like the technique used to paint the mold when making multicoloured chocolates.

maybe you could streak the mold with a little bit of white soap drizzled from a spoon. make "fat stripes", but leave gaps. let it harden a bit. then pour red soap to fill the whole mold with "meat"- the red will show red through the gaps you left when you applied the white streaks. let it harden a bit. lastly, take a bit more white and streak the top side of the bacon with "fat".

not sure how fast the soap hardens, so this may not be practical- maybe making plain red strips, then unmolding them and painting white on them by hand is the way to go. either way, i think the key lies in making the fat streaks superficially.

I think laying down two separate layers of fat and meat like your suggesting is a good idea. All my soap hardened at the same time, but staggering the batches a bit so you could lay down first the fat and then the meat would probably result in some great marbling. Superficial painting of the bacon might get a bit complicated since the soap actually wears down pretty quickly and you would lose the marbled effect after the first few uses. I think some combination of the piping system suggestion that crapflinger suggested coupled with a two part marbling process would be what I will try in my next batch of bacon soap. Should there ever be another batch of bacon soap... Thanks!

If you use the fat to make your soap, what are you going to use to fry your eggs the next morning???
Tyler Durden: The salt balance has to be just right, so the best fat for making soap comes from humans.
Narrator: Wait. What is this place?

I noticed you used ice cube molds for the soap. You can also use candle molds, soap molds, or chocolate molds. Just find the shape you want. Or line a square container, like tupperware, with plastic wrap, pour soap in. After it hardens, remove soap block and cut it into rectangles.
I was thinking you could use some of those antique cast iron or steel muffin pans. Some are made in unusual shapes.

I`m a part time teacher in vocational school in Finland and we made soap in our laboratory. The used oil should be long chained fat. for example risin oil.(not sure for the right translate). we also added salt(NaCl). but when you make soap in home I ques the salt containing in the household water is enough.
thepelton forra4 years ago
The salt or other additives to the local water would vary from one area to another. I recall that there was a distinct aroma of sulfur in the tap water in Steamboat Springs, Colorado.
forra thepelton4 years ago
and i just found out that the meaning of adding salt is to help separate the formed glycerin. so it is not necessary.

A bacon fat bomb sounds kind of nasty and anarchistic. I'm glad you decided to go to making soap.
