How Do You Make Lye Soap From Scratch?
To make lye soap from scratch, you’ll need lye, water, and fats or oils such as coconut oil, lard, or olive oil. First, mix the lye and water in a non-reactive container, preferably a heat-resistant glass or ceramic one. Once the lye has dissolved, heat the fat or oil in a separate pot until it melts. Then, slowly pour the lye solution into the melted fat, stirring constantly. The mixture will begin to thicken and eventually reach “trace,” a point where the soap mixture can hold its shape. Once it has reached trace, pour it into soap molds and let it sit for a day or two before cutting it into bars. Let the bars cure for several weeks before using them.
