Goat milk and honey soap - and a natural soap book review

I've been wanting to try making soap with milk for ages.  We haven't been milking our cows, so I was waiting for a friend to have enough goat's milk to spare.  I know I could just buy milk, but that seemed like a strange thing to do (you start to forget that milk comes from the shop when you've been milking a cow for a few years!).  Anyway, I was happy to wait as I had plenty of other soap to make.

While I was waiting, I also received a review copy of a new soapmaking book called The Natural Soap Making Book for Beginners: Do-It-Yourself Soaps Using All-Natural Herbs, Spices, and Essential Oils (Affiliate link), by Kelly Cable of the blog Simple Life Mom.  Kelly has an amazing Etsy shop full of soaps and natural lotions, so I am very excited that she has decided to share her experience and recipes in this book.  And seeing as it contains several goat milk soap recipes and my friend finally had some goat milk to spare, I recently got my chance to try goat milk soap.  Even better, I have permission to share one of the recipes with you today. The book will be released on August 8, 2017, but is available for pre-order on Amazon now (if you order before August 7 you can head over to the Natural Soap Bonus Collection and get a host of extras - giveaways, printables, how to videos).

The trick with milk soap is to start with very cold milk, some people freeze it completely before adding the caustic soda.  Kelly also recommends only replacing half the water with milk, in her recipe below it is less than half the milk.  She also includes honey for lather and beeswax for hardness (as well as a slight tan colour and honey fragrance).  The recipe uses lard, but I asked Kelly if I could swap that for tallow as I always have plenty of tallow, and she said that would be fine.  It is a little more adventurous that my usual recipes, as it also has sweet almond oil for lather.  The main scent is orange essential oil, which is lovely with the slight honey smell from the honey and beeswax.  I usually only use tallow, olive oil and coconut oil, so it was a nice challenge to use some different oils and ingredients to try this recipe as part of my book review.

Apart from several goat milk soap recipes, there are over 200 pages, covering everything you need to know about natural soapmaking, including natural colourants, techniques for swirling and specialty bars that are more than just soap.  Most of the recipes use either tallow or lard, with coconut oil, olive oil and various specialty oils and butters.  I often find that I have to adjust recipes to incorporate tallow, as it is my preference for soap making, so it was a nice change to have a whole book of recipes designed for tallow and lard already.

The only issue from my end was that everything was in ounces, so I had to convert each recipe before I started.  An ounce is 28g, so you just need to multiply each ounce measure by 28 to get grams, or there is a conversion table at the back of the book.  I checked the recipes with my own calculations before I used them to make sure that I got the conversions right.  Its good practice to do this with any new recipe, using your own calculations or an online soap calculator, just to be sure as you never know if there have been typos or miscalculations (although I'm sure this book has been triple-checked for such things, but you can never be too careful!). 

I had already read a bit about goats milk soap, so I was prepared for a few of the things that happened when I made the soap.  First, the lye solution had a slight ammonia smell, which is normal.  Second it started to thicken, due to the small amount of fat in the milk, so I just had to keep stirring until it thinned out again.  Finally, I found that the soap reached trace very quickly.  This was partly my fault as I let the caustic solution cool to 30degC before adding it to the fats.  They were still 50degC due to the beeswax needing a higher temperature to melt.  When I combined the cooler caustic solution with the fats some of the mixture started to solidify and I had to mix it with a fork and fortunately I was able to keep it in a liquid state and was able to pour it into moulds.  This is the first time this has ever happened to me.  For this reason I would say that this is a recipe to try after you have made a few easier soaps, as using beeswax and shea or cocoa butters does required the fats at a higher temperature which can be tricky.  I added calendula petals to the top of half the soaps.

I also made a plain tallow and goats milk soap just to see what it was like and a goats milk shampoo bar from the book.  The second one contained honey (I think I added too much) and made the soap a darker colour.  I'm looking forward to trying all of the goats milk soaps to compare them and it was a lot of fun using a different ingredient.  There are plenty of other recipes in the book that I want to try, especially the chapter on natural colouring agents and decorative techniques as my soaps so far have been quite plain.

Though a Castile bar was the first soap recipe I made, I dreamed of making a Goat Milk and Honey Soap bar. Well, here it is. Using milk and honey in a recipe means you need to be aware of a few more things, but it’s pretty easy once you get the hang of it. Enjoy the many nourishing benefits of this soap!

Equipment list:
Large stainless steel pot
large spoon
bowls for measuring ingredients
stick blender
small zip top bag
glass or plastic bowl for lye water
parchment paper
rubber spatula
measuring spoons

· 10 ounces olive oil
· 8 ounces lard
· 8 ounces coconut oil
· 4 ounces sweet almond oil
· 2 ounces beeswax
· 4 ounces lye
· 8 ounces filtered water
· 4 ounces goat milk
· 1 ounce orange essential oil
· 1 Tablespoon raw honey

Safety First!
Remember to wear your safety equipment and mix the lye water outside.
Tell everyone you live with that where you're working is off limits.
Give yourself enough time to complete the recipe.
Prep Ahead: Combine the water and milk in a large glass, plastic, or stainless steel container. Place milk-water into the freezer for 1 to 2 hours. It is okay if a slush forms, as long as it doesn’t freeze. The colder your milk-water, the lighter your soap will be after adding the lye.
1. Heat the Fats/Oils: In a large pot over medium-low heat, combine olive oil, lard, coconut oil, sweet almond oil, and beeswax. Heat until they are melted and incorporated. Remove from heat and allow to cool to 90-100°F.

2. Mix the Lye-Water: Put on protective gear including a mask, gloves, and long sleeves. Outside, very slowly pour only ¼ of the lye into the milk-water and stir until dissolved. Let cool for 20 minutes. Repeat until all lye is dissolved into the milk-water. If milk still browns, don’t worry. Your soap will just be darker. Allow to cool to 90-100°F. If oil or lye water cool at different rates, you can use a cold or hot water bath in the sink.
3. Prepare the Mold: While the oils and lye water cool, line the mold with parchment paper.

4. Combine and Bring to Trace: When both oils and lye water are around 90-100°F, pour the lye water into the pot of oils. Use a stick blender or hand mixer to mix for 1 to 2minutes and then let the mixture rest for 4 to 5 minutes. Repeat mixing and resting until light trace.

5. Mix in Natural Additives: When soap reaches light trace, add essential oils and honey and blend for 30 seconds.
6. Mold the Soap: Pour the soap mixture into the mold, cover with a lid or parchment paper for 24 hours. Do not insulate unless your house is below 75°F, then insulate by placing a towel around the outside edges to avoid a partial gel.
7. Cut and Cure: Remove soap from the mold. If it seems too soft to remove, wait another 12 to 24 hours before removing. Cut the soap into twelve 4-ounce bars. Allow the bars to cure for 4 to 6 weeks.
Tips: Milk can scald when lye is added. Placing the milk-water in the freezer until it’s very cold helps prevent this. Be sure to add lye slowly. It is okay to really take your time, coming back every 20 minutes to add a little more. Adding milk can also make your batch get hotter than usual, so just insulate a milk recipe lightly with a towel if you’re concerned about getting a good gel for color. Honey can also make soap come to trace faster, so add it and blend really well right before pouring soap into the mold.

Have you tried making goats milk soap?  Any tips or techniques that can help?

**This book was sent to me to review and I made the recipe myself to test it.  Thank you for supporting my blog by using my affiliate links**


  1. I too have made soap with milk (cows) as well as honey and egg and it does take practice to learn what will speed up trace. Honey is notorious for that, so like you said the colder your milk the better. I do freeze it completely and add my lye a little bit at a time. The end product though is well worth the trouble and your soaps are gorgeous!

Worm farm maintenance

I have had the worm farm for over a year now, and I have to say it’s the easiest and most convenient way I have found to make compost and to dispose of vege scraps and other organic waste. I have not had much success with putting everything in a compost bin, I find that the food scraps go all sloppy and don’t really compost properly. I have found that my current system works much better, all food scraps go to the worms and the compost bin is for weeds and manure. The worms are able to eat all our food scraps and convert it to compost and worm tea, and there is still plenty for the compost bin, but now its not full of sloppy food scraps. People often ask if its necessary or possible to have both a worm farm and a compost bin, and I think it actually works better for us.

The worm farm really requires very little maintenance.  All I have to do is tip in more food scraps every few days, drain the tea once a week or so, check that the top tray is damp (if not, tip in half a bucket of …

Getting started with chickens - Tanya from Lovely Greens

Sign up for my weekly email updates here, you will find out more about soap and our farmlife, straight to your inbox, never miss a post!  New soap website and shop opening soon....

Farmer Liz: You will remember Tanya from Lovely Greens from the first series, she lives on the Isle of Mann and added chickens to her garden about a year ago.  You can leave comments for this post on Tanya's blog.

How many chickens (and other fowl) do you keep, what breed and what do you use them for (meat, eggs, slug control etc)?
Tanya: Around the same time that we were initially thinking about having hens another friend beat us to the punch. She went to the local pet store and bought a flat-pack hen house and chicken run combo and found a local farmer who had dozens of semi-feral chickens running around his property. One night he pulled three down from the trees and my friend took them home in a pet carrier. She named them Miracel, Carmen, and Geraldine and though they’re probably related they were all…
