According to The Soap Queen, Hot process is a great soapmaking method when you want to enjoy your soap quickly. The main difference between hot process and cold process soap is that hot process soap is “cooked,” which speeds up the saponification process. This results in a loaf of soap that can be cut and enjoyed the same day. That being said, I always recommend a couple weeks of cure time to help water excess water evaporate and create an even firmer and longer lasting bar. And Hot process is usually made in a slow cooker, but can also be done in a double boiler. If you want to try a small batch of hot process soap, then try a recent post of a recipe called Snowdrop Hot Process Soap.
