Jump to the recipe for coconut oil and soy butter soap
When I first called Natalie Pepin, I told her I really wanted to learn how to make soap.
“But I’m afraid of lye,” I confessed. I suggested maybe we should do candles instead.
“No,” she told me. “Let’s do soap.”
Pepin is a Harvard Extension School graduate who, after completing her studies, decided to return to homestead in Alberta and now lives with her family in an off-grid cabin in the province’s Tawatinaw Valley. Through her business, ReSkilled Life Learning Centre, Pepin teaches a variety of homesteading skills, Indigenous arts and ancestral crafts, including tanning and beading, moccasin making and soap.
“These skills weren’t only practical. They hold clues into the lives of our ancestors,” Pepin says. “They tell us about their character, about how they got through difficult times and the things that were important to them.”
Pepin says she has always been “very artsy” and started learning traditional arts and skills as a way to connect with her Métis culture, particularly around the work of women, a part of history not always documented.
Although Pepin was passionate about environmental studies and business during her time at Harvard, she says she felt drawn to the work she could do at home preserving traditional skills and knowledge and sharing the foundational human skills “that allowed us to exist and got us to this point in time.” She says her final project at school was titled, “From Harvard to Homestead.”
Pepin says many people are – like me – both interested in, and intimidated by, the prospect of soap making from scratch. While it does involve working carefully and taking some basic safety precautions (like wearing gloves and goggles), she says most people are surprised at how safe and simple it is. Her experience is reassuring.
“Soap is kind of magical in that you’re taking two or three very different ingredients and combining them and they turn into something different,” she says. “... There’s a chemical reaction, there’s a process that takes place. And it’s like alchemy, you create something different. And I think that’s interesting to people.”
Pepin says she thinks many people are interested in soap making because it’s a practical thing we use every day and an economical, artisanal skill we can easily adapt to our own tastes and preferences.
She points out that soap making was a traditional practice of the Métis and of cultures all around the world, one of those fundamental and essential skills that she says can connect us with each other and our broader human history.
“It feels so old school to say I’m going to make soap, and there’s a piece of pride in maintaining those old skills,” she says. “It makes you feel connected to the things before you.”

Globe Craft Club Lesson two: How to make soap
- 30 oz by weight of fat (in this recipe, a mixture of ¾ coconut oil and ¼ soy butter). You can find recipes online for different kinds of fats, which may affect the lye-fat ratio, so don’t substitute different types.
- 11 oz by weight of distilled water (distilled water ensures consistent results, though you can use filtered water or tap water that’s sat on the counter for several hours).
- 3.88 or 3.9 oz by weight of lye (find in the soap-making area of a craft store, in the drain-cleaning section of a hardware store or order it online – look for pure lye crystals only). Lye is a caustic substance, so wear safety protection such as glasses, gloves, and long sleeves during the soap-making process and exercise caution when working with the lye. If any lye touches your skin, dabbing with white vinegar will help stop the burn.
- Colorants, scents or other add-ins. Pepin advises using natural ingredients such as essential oils, rose petals, calendula, charcoal powder, coarsely ground coffee, matcha powder, oatmeal (either whole or quick), herbs or spices such as cinnamon, cloves and nutmeg (though nothing that will irritate your skin like chili pepper powder). Any plant matter needs to be very dry otherwise it’ll rot in the soap. For scenting it takes a lot of essential oils for the smell to come through (and don’t add essential oils when the mixture is hot or the scent will burn off). To colour the soap use charcoal, ground rose petals, French green clay, pomegranate seed, beet powder or soap colorants. Don’t use food colouring or vanilla because they won’t disperse into the oils.
Any of this equipment can be what you already use for cooking or food preparation. Only use non-reactive materials such as plastic, heat-safe glass or stainless steel. Don’t use aluminum or copper because those will cause a reaction with the lye and affect the quality of the soap.
- 3 heat-safe measuring cups or mixing bowls, 1 litre or bigger
- Wooden spoon
- Measuring cups
- Measuring spoons
- A sensitive digital scale. A bathroom scale will not work. A regular kitchen scale will work if it is sensitive enough to measure 0.1 oz increments.
- A silicone bread-baking pan or soap moulds (the soap will stay in the mould a week or two, so use something you can do without). Silicone trays are easy to unmould, but if you’re using a plastic mould it’ll need to withstand heat – avoid yogurt or to-go plastic containers. A cardboard box or thin metal pan will also work, but the soap will stick so use parchment paper or wax paper as a liner so it’s easy to remove afterward. Milk cartons would also work. Don’t use glass because it won’t unmould easily.
- An immersion blender or wooden spoon
- A large pot or slow cooker for warming oil
- A kitchen thermometer (a candy thermometer if you have, but a digital thermometer is also fine. A medical thermometer will not work)
- Rubber gloves (dish gloves or disposable)
- Eye protection
- Rubber spatula
Warm oil in a pot until it’s melted, stirring every once in a while. You don’t want to get it anywhere close to boiling – you are only warming it. The temperature needs to be between 37-51C and no hotter. Once it’s liquid, turn the heat off and let it sit.
Wearing eye protection and gloves, use a stainless steel spoon to measure the lye and place it in a plastic, heat-safe glass or stainless steel container. Never pour water into the lye because it will create a violent reaction. Instead, slowly pour a slow, even stream of lye into the water, then gently stir the mixture with a wooden spoon until the lye has fully dissolved (don’t put the wet spoon back into the lye crystals). Don’t place your face close to the lye-water mixture as you’re stirring because the mixture may produce steam and vapours.
Continue mixing with a wooden spoon until the lye has dissolved and there are no crystals left. The mixture will be hot so let it sit to come down in temperature – keep stirring to help it cool. The lye solution and oil need to be similar in temperature – 37-51C, though they can be within 10-15C of each other. Check the lye solution with a kitchen or candy thermometer to make sure it’s in that range. If it is, check the temperature of the oil mixture.
Take the oil off the heat before proceeding to mix with the lye. Start by slowly adding the lye solution to the oil in a steady stream as you gently stir with a wooden spoon. Don’t pour all the lye in at once because you don’t want it to splash.
The mixture will start looking cloudy and eventually begin turning white. You can continue to stir with the wooden spoon, or switch to an immersion blender, which is much quicker. (Stirring by hand will take about 15-20 minutes, stirring with a hand mixer around eight minutes or less, depending on the oils used.) Take breaks to allow the immersion blender to cool down if it is overheating.
If using the immersion blender, hold it on an angle at the bottom of the pot. Make sure it’s deep enough so the bottom of the stick blender is immersed and begin blending on the lowest speed, being careful to avoid any splashing. Keep stirring until you can see the lines made by a spoon and they don’t disappear – that means the mixture has reached tracing, which indicates the beginning of saponification. The soap will begin to harden quickly after that, so add any other ingredients such as scents or colorants and stir a few times to incorporate.
Spoon soap into the mould. Once it’s halfway full, pick up the mould and tap it on the counter to get rid of any air bubbles. Fill the mould all the way, then smooth the top. You can sprinkle the tops with dried herbs or flower petals for decoration if you like. Carefully place silicone moulds on a cookie sheet or cutting board before transferring so they don’t move around or spill when you lift them.
The soap needs to sit 48 hours to a week to set before unmoulding. Leave it in a place that isn’t too hot or cold, such as a linen closet, and keep it out of the way so it won’t be disturbed. To test, touch it with your finger. If it indents, leave it to sit longer. Times may vary depending on the oils used.
Once the soap is set, unmould it. If using a big mould, cut the soap into individual bars. You can use a soap-cutting knife, which looks like a pastry scraper, or a sturdy kitchen knife – thinner knives cut through soap more easily. Score the top so you know where to cut before you start slicing. It’s helpful to wet the knife and clean it off between each cut to keep your slices smooth. Go slow – smooth and even cuts make the best bars. After cutting, you can stamp the bars with anything from around your house.
Space your bars of soap out on a cookie sheet or cutting board so air can circulate around them and let sit to harden for at least a couple more weeks before using. The soap will get harder after a couple of months.
