MILK PREP: When lye is added to milk, the temperatures heat up to 200 ° F. This scorches the milk, causing it to smell bad and develop a dark yellow color. Keeping the temperatures as cool as possible helps prevent that scorching. Our preferred technique is to freeze the milk into cubes before adding the lye. To keep the milk extra, extra cold, you can place the container of frozen milk into a larger container with ice. First, measure out 5 ounces of milk and pour into ice cube trays. Allow the milk to fully freeze. Next, empty the milk ice cubes into a container appropriate for mixing lye. When adding the cubes to the container, place the container on a scale to make sure you have the correct amount of milk. Although it was measured previously, some milk might be lost in the freezing/transferring process. If you’re short, pour cold milk into the container to supplement what you have. Adding distilled water to supplement works too.

MOLD PREP: To create the flower shape on top of each bar, we used the Flowers and Spirals Impression Mat. Use a sharp pair of scissors to carefully cut out individual flowers from the mat. Then, place them pattern side up into each cavity of the Silicone Scalloped Round Mold. Set aside.

SAFETY FIRST: Suit up for safe handling practices. That means goggles, gloves, and long sleeves. Make sure kids, pets, other distractions, and tripping hazards are out of the house or don’t have access to your soaping space. Always soap in a well-ventilated area.

LYE PREP: With safety gear on, slowly add about ¼ of the lye flakes directly to the frozen milk. Use a non-reactive spoon to stir the lye flakes and milk together. Slowly, the flakes will begin to melt the cubes. After a few minutes of stirring, add another ¼ of the flakes and continue stirring for several minutes. Continue this process until all the lye flakes have been added to the milk. The milk will continue to melt as more lye is added and stirred. Once the milk has fully melted, continue to stir to make sure all the lye flakes have completely dissolved. Because the temperatures are low, the lye flakes do not dissolve as quickly. Listen and look for lye flakes on the bottom of your container; lye flakes can take a lot longer to dissolve in cooler temperature liquids. Patience is key. Any undissolved lye in your soap could cause skin irritation or even lye burns, so take extra time to make sure all the lye is dissolved. If you’d like a harder bar of soap that releases faster from the mold, you can add sodium lactate to the milk solution. Use 1 teaspoon of sodium lactate per pound of oils in the recipe. For this recipe, you’d add 1 teaspoon sodium lactate.

COLOR PREP: Disperse ½ teaspoon of titanium dioxide into ½ tablespoon of lightweight liquid oil, like sweet almond oil or sunflower oil. Then mix 2 teaspoons of French green clay into 2 tablespoons distilled water. Use a mini mixer to get rid of any clumps. NOTE: To ensure that the titanium dioxide blends smoothly into the soap batter, we recommend micronizing it before dispersing it in oil. Please note this is an optional tip but it does help with the titanium dioxide clumping in the soap. To micronize colorant, simply use a coffee grinder to blend the colorant to break up any clumps of color and prevent streaks of white from showing in the final soap. We like to use a coffee grinder that has a removable, stainless steel mixing area for easy cleaning.

FRAGRANCE PREP: Measure 0.6 ounces of lemongrass essential oil and 0.4 ounces of tea tree essential oil into a glass, essential oil safe container. Set aside.
