Hot Process Goats Milk Soap
Ingredients
9.6 oz Crisco
9.6 oz Olive Oil
6.4 oz Lard
6.4 oz Coconut Oil
12.16 oz Goat's Milk
4.463 oz Lye
Gather all tools, utensils, ingredients, and other supplies including your molds and prepare your work area.
Step 1
Weigh your goat’s milk and place in the freezer. Wait about an hour, with the milk chilling in the freezer, then move on to Step 2.
Step 2
Weigh each fat/oil. Place fats/oils in a crock pot on Low. Heat until completely melted. Turn the crock pot off. Remove crock from pot and place on a wire rack to cool.
It’s not necessary to take the temperature of the mixture–just let it cool while you move on to Step 3.
Step 3
Put on your goggles and gloves. Weigh the lye. Remove the milk from the freezer–it should be very cold by now, like a slushy. It doesn’t need to be completely frozen. Begin to gradually add the lye to the milk. DO NOT add very much at a time. ALWAYS ADD LYE TO THE MILK, not the other way around. Adding the lye to the milk should take about 45 minutes. This keeps the entire mixture at a controlled cool temperature during the combining of the milk and lye, and is a key part of the “cold process treatment” you’re giving to the hot process soap.
Over the course of the slow lye addition to the milk, the mixture will turn yellowish.
By the time you’re finished, it will be a lemon-y color. With your crock back in the pot (heat still off), it’s time to combine the lye/milk mixture with the melted and cooled fats/oils.
Step 4
Carefully pour the lye/milk mixture into the fats/oils and begin stick blending.
Once you reach a nice, strong trace, it’s time to turn the crock pot back on Low.
Step 5
Put on the lid, but check back frequently. Early in the cook:
As the mixture turns from the outside in into a gel state, the extra and variable fat in goat’s milk can separate.
This is one of the tricky aspects of a milk soap. When using fresh farm milk, it’s impossible to account for the exact amount of cream content in the milk, especially goat’s milk which is homogenized and not readily skimmed. Basically, it’s extremely super-fatted. Put the stick blender back in the crock and re-emulsify it.
The rapid re-emulsification with the stick blender will speed the finish time, and help keep the soap from over-cooking or darkening or getting a cooked-milk stink.
Step 6
Before placing hot process soap in the mold, I always transfer it first to a stainless steel bowl. This is where I mix in additives and fragrances. I like to get it off the heat as quickly as possible. If you’ve paid attention to your soap and not over-cooked it, it will still be in a smooth and workable state for another 5-10 minutes. Especially if I’m adding fragrances, I like to stir the soap around and cool it slightly before adding scents.
Step 7
Place the soap in the prepared mold.
Put the soap in the freezer. This quick cool-down will further interact with the rest of the “cold process treatment” we’ve given this hot process soap to keep the color lighter by kicking back the heat on the soap as quickly as possible. Leave it in the freezer for at least two hours before removing. Let the soap come to room temperature before unmolding.
Here is the finished soap, unmolded.
Now just cut into bars!
