How To Make Homemade Soap

Equipment and ingredients

Kitchen scale
Stainless steel thermometer
Gloves, protective eyewear, face mask
Hand blender
Stainless steel pot
Mixing bowls
Measuring cups and spoons
Stainless steel spoon
Silicone spatula
Soap mold
Parchment paper
Towel

INGREDIENTS
Coconut oil
Olive oil
Lye(sodium hydroxide)
Coffee
Coffee grounds
Oat bran

Measure and mix
+ Using a kitchen scale, weigh out 8.48 oz coconut oil in a stainless steel pot.
+ In a bowl, measure 12.48 oz olive oil.
+ In a second bowl, measure 7.9 oz coffee.
+ Measure 3.22 oz lye in a third bowl.
+ Measure out 1 tablespoon coffee grounds and 1/3 cup oat bran in a fourth bowl; set aside.
+ Put on protective gear, and make sure you are in a well-ventilated area. Add the lye to the coffee, and stir to dissolve. (Always add lye to liquid, not the other way around.) This will start a chemical reaction, and the mixture will get quite hot. Set aside. You may remove eyewear and face mask at this point, but gloves should remain on.

Emulsify
+ Melt coconut oil over low heat until no solids remain. Add olive oil.
+ Using a stainless steel thermometer, check the temperature of the oils. Compare against the temperature of the lye solution, and adjust until they’re within a degree or two or each other, between 100 and 110 degrees.
+ Pour the lye solution into the oils, and use a hand or stick blender to emulsify until the mixture begins to thicken and the texture resembles pudding. This process will take 5 to 10 minutes with a stick blender.
+ Once the soap has thickened, stir in the coffee grounds and oat bran with the stainless steel spoon or spatula.

Pour and rest
Slowly pour the mixture into a soap mold. Lift and tap the mold against the counter a few times to release air bubbles. Cover with parchment paper, and then wrap the entire mold with a towel to insulate it.
Remove from mold
After 24 to 48 hours, remove the towel, and take the soap out of the mold. If you used a large single mold rather than individual molds, let the soap loaf sit for another day to harden further before cutting into bars. Any sharp knife will work here. A vegetable peeler can be used to smooth sides, if desired.

Cure
After the soap is cut into bars, you’ll need to let them cure in a cool and well-ventilated area for four weeks. This allows the soap to finish saponification and for all the excess water to evaporate. Before you know it you will be able to enjoy your soap!
