Step One: prepare lye
Using a digital scale, measure out the lye and coffee in separate containers. The coffee must be cooled to room temperature before adding the lye. Stir carefully until the lye is completely dissolved into the coffee. The liquid will shoot up in temperature and emit a burned-coffee scent. Place it aside to cool in a secure location out of the reach of kids or pets.
Step Two: Melt oils
Measure the oils individually, then mix them together in a large pot. Melt them over medium-low heat until fully melted. Set aside to cool.
Step three: Blend and pour
Once the coffee solution and oils have both cooled to about 100-115 degrees, it’s time to blend. Get out your coffee grounds, soap molds, and any fragrance or color you’ll be adding. Pour the lye water into the pot with the oils and blend with your stick blender until you reach trace. Stir in coffee grounds once you’ve reached trace. If you’re using fragrance or color, mix them in by hand. Working quickly, pour into the soap mold.
Step FouR: Cure and cut
Allow the soap to cure in the mold for 24-48 hours before removing it. Cut into bars after slicing. Before using, let it sit for at least 3 weeks and store it in a well-ventilated area.
Homemade soap is happiest in a cool, dark place with plenty of air circulation. I like to put it in a cardboard box with newspaper and tuck it on a closet shelf.
It will last basically forever if stored well.
It doesn’t matter. Just use what you have on hand. If you have a type of coffee you don’t like anymore, use that!
Yes, you can!
Nope. The finished bar has no fragrance.
No, since there is sugar in the coffee it will behave just like water when you add the lye. You’ll notice the scorched smell and (obviously) the color, but that’s it.
👩🏻🍳 Expert tips
